Part one
The Doctor and Nyssa land on a planet on instructions from the Time Lords. The Doctor has been tasked with a mission to convince fellow Time lord, the cardinal Zero, to return home and take his place on the high council. The native species on the planet appear to be an avian species. The Doctor and Nyssa stumble onto an ongoing trial for Redklaw who stole food but a child of the species is publicly injured as well because the law dictates that the guilty party as well as one of their closest of kin whom they care about most must be punished and Nyssa impulsively interferes, ignoring the Doctor's warning. While trying to calm the situation, the Doctor discovers that they have been expecting him.

When they are brought to the city in the trees by Carrion, she explains that Zero had concluded that the Time Lords would send the Doctor to persuade him to return. They are brought before Zero and throughout the course of the conversation many surprising facts are revealed to Nyssa about the Doctor. More importantly, the Doctor explains that the Time Lords have sent him because the native avian species on the planet have been developing at an alarmingly unnatural rate and they "trust" the Doctor's judgement to survey and potentially deal with the situation. Zero assures the Doctor that he has not interfered in any direct way in their evolution and attempts to persuade him that he simply lives among them, despite the fact that they refer to him as their "prophet" and that he is trying to help them "return to the sky". He then takes them to the hatchery and explains the intricate symbiotic hatching process of the avian species, including a plant called the Yolk of Darts, a yellow flower that is dangerous and poisonous enough to cause a Time Lord to regenerate and acts as a defense mechanism for the hatchery. He then points out the great city of "Platch" to them, explaining that they will be going there tomorrow because Zero is to act as a judge, jury and executioner because a murder has occurred there for the first time in six years. The Doctor is disgusted with this but there is nothing much he can do for now and so begrudgingly agrees to accompany Zero tomorrow and retires to his sleeping quarters, a nest, for the night.

That night, the Doctor is quietly visited in his temporary nest quarters by Snowfire, who explains that her father Willowsap, is the avian being judged tomorrow because he had a dispute and killed a neighbour, being prone to moods since her mother died. However, since she is his closest living kin most precious to him, she will almost surely be killed as well since the whole neighbourhood saw her father commit murder and he will most surely be judged guilty. She further explains that the entire population reject the current system of justice, believing that the innocent should not have to suffer the crimes of the guilty, however, they cannot operate outside the law and the Doctor now realises what Zero meant by "not interfering", in that he won't interfere preferring to keep things the way they are currently. He promises to help her and tells her to leave for now.

Nyssa, awoken by the stir, finds the Doctor who tells her they need to enact a plan quickly and he has something in mind. He then instructs her to go back to the TARDIS. The Doctor then visits Zero in his room and wakes him up, only to find Zero "acting", exclaiming that the Yolk of Darts has been brought to his room and "accuses" the Doctor of having brought it (while the gloves from earlier lie in the corner, Zero brought it himself) and the Doctor realises that he has been set-up by Zero. Zero, while shouting, touches the fruit and "dies", falling into the river where his TARDIS is located, buried at the bottom. He then re-emerges, having regenerated into one of the avian species and the Doctor notes that the plant must've altered his Gallifreyan DNA to be partially avian. Carrion arrives to inquire what happened and Zero explains that he killed their "prophet" (ie himself), and that in order to be punished, according to the law, the Doctor, his closest living "relative" (since they are the same species) must be killed as well. The Doctor, picking up on the hint, flees with Nyssa and they get back to the TARDIS in time to take off. Zero explains that with no way to punish the Doctor, and since he will never return, he cannot be punished as well, meaning that this calls for a revision of the entire justice system. He explains that there must be an immediate pardon for all awaiting trial, thus sparing Snowfire and himself, and that they will begin to base justice only on punishing the guilty party, while meanwhile it is revealed that the Doctor, having realised Zero's plan, went along with it as well, as Nyssa later realised.

Part one
The Doctor ponders over circular and linear time while watching a cricket match of which he is a participant September in Stockbridge with the Stockbridge Cricket Club, drawing parallels between them, real life and the game as he has brought himself and Nyssa here for a vacation. Nyssa approaches him and laments that she can't seem to finish her novel but the Doctor tells her to keep at it.

Over the next few days, Nyssa continues to try writing her novel in a bar but is continually interrupted by Andrew Whitaker, slowly becoming more and more annoyed by his intrusive inquiries while the Doctor practices with the Stockbridge Cricket Club team for an upcoming match. Later Andrew drives Nyssa to Traken, which turns out to be a village farther out from Stockbridge, thinking he is taking her home after she told him where she was from. She reveals to him that she is an alien, and although perplexed he has other intents on his mind and kisses her. Nyssa reveals this is her first kiss. Meanwhile, the Doctor attends the pub with the team to discuss strategy but slowly they reveal their racist attitudes, especially Jack, the team coach. The Doctor, disgusted, leaves the pub and ends up bumping into Nyssa and Andrew in the forest on his way back to the inn, questioning Andrew's intentions and then leaves them (it is very heavily implied that Nyssa and Andrew have had sex). She finds she has fallen in love with Andrew despite her best efforts not to.

The next day they attend the big match, after Nyssa reveals to the Doctor she has decided to go the village Cricket Club ball, having earlier expressed displeasure at the thought. At the match, she sees Andrew in a new light, becoming upset with his candid attitude and simple-minded pursuit of her, and explains to him that she understands now what it is she doesn't like about him. She explains that he has no regards for consequences and that this will come back to hurt him down the road. She then tells him it's time they get ready for the ball and they set off.

The final stretch sees the Doctor's Stockbridge team win, however, Don, one of the runners, dies in the process having been under the weather throughout the game. Andrew, returning to the bar to pick up Nyssa after getting ready, finds that the ball has been cancelled because of Don's death and that Nyssa is nowhere to be found. Instead, on the table she had been working at throughout her stay, he finds her completed novel and begins to read it.

Part one
The TARDIS, carrying the Doctor, Tegan and Nyssa, gets taken off course after a heavy dose of smog interferes with its systems during travel and crash-lands near Manchester. They are found by Hurley family servant Cathy Roberts, and her masters William Hurley and his father Mr. Hurley. Cathy discusses the event with her father Roberts and he forbids her from going to the protest tomorrow, citing behaviour like this is leading her to strange and dangerous situations. After getting some rest, they wake up and meet industrialist and engineer Mr. Hurley, who learns about the TARDIS (which he is told is a ship) and gets some men to bring it back to his estate, interested in it for his own ends though. The TARDIS is heavily damaged and the Doctor informs Tegan and Nyssa privately that the self-repair will take a day before they're ready to go. Hurley offers the Doctor a tour of his factory who, intrigued, agrees and brings Tegan along while he asks Nyssa to stay with the TARDIS in case it needs some assistance in its self-repair. Inside the factory they learn Hurley is employing children and one of them gets injured and trapped in one of the machines, and the Doctor, ignoring Hurley's warning, goes down to the factory floor to save him. Cathy meets Nyssa but is told off by Mrs. Hurley who then introduces herself to Nyssa.

The Doctor manages to save the boy much to Hurley's annoyance and attempts to treat him despite Hurley's insults and indifference, preferring to simply dismiss him. Tegan volunteers to head into town to look for medical supplies for the Doctor since Mr. Hurley doesn't keep them around for his employees and she is unwillingly accompanied by William Hurley while the Doctor says that he and Mr. Hurley need to discuss the way his factory is run. Mrs. Hurley finds out about the march that Cathy intends to go on tomorrow and dismisses her and while Nyssa tries to defend her and calm the situation, Mrs. Hurley kicks her out as well. The Doctor, in his discussion with Hurley, discovers the chronometer was badly damaged and that they're not in the time he thought, but are in 1819, on the eve of a very dark day in history...

Part two
The Doctor is dismayed to discover they've landed in the hours leading up to the Peterloo Massacre and his friends have gone out to wonder freely before the event is about to take place, putting themselves inadvertently in grave danger. Tegan and William Hurley argue about the state of the city and the poor people as their views are completely opposite. Cathy takes Nyssa back to her house and meets her baby brother Peter. Cathy talks about her hardships and they compare backgrounds after which she tells her that there will be a large gathering tomorrow and convinces her to come. It turns out William Hurley is an officer in the private defense force/militia, a force that is funded by his father's factory. The Doctor meets Mrs. Hurley who explains she has fired Cathy and dismissed Nyssa. Nyssa, after listening to Cathy, agrees to come out with her to the protest tomorrow. Tegan is locked up after being found by captain Walton and accused of being a saboteur and that William Hurley lied about his position, being a lowly lieutenant. The Doctor goes to Cathy's house and meets her father who tells him she's likely to be found at the big gathering taking place and he runs off. He bumps into William Hurley on his way with his friend, investigative journalist Thomas Tyler. He explains what happened to the Doctor and the Doctor joins him in the carriage back to the estate to check on Nyssa. Nyssa is gone and the Doctor demands that they go into town before something bad happens, despite being reassured by William Hurley nothing can and will. Nyssa and Cathy join the protestors and as they walk, she learns that her baby "brother" Peter is actually her son and she was arrested the previous year for trying to give out advice to women about unwanted pregnancy, on charges that she was distributing propaganda. The Doctor manages to find and get to Tegan in time and explains to her that they need to leave immediately as they are about to witness the Peterloo massacre...

Part three
Tegan and the Doctor encounter Reverend Small who explains he has come to quell the gathering protest by reading out the riot act. The Doctor explains to Tegan that this is how the event escalates, that if the protest doesn't disband after hearing the act then the cavalry can be called in to "handle the situation". Small begins reading in a place that no one can hear him. William Hurley, with his father, asks what Small is doing and Mr. Hurley explains he's reading out the riot act. William argues that no one can hear and that it's not fair but Mr. Hurley takes no notice, telling him he has to do his job. Nyssa gets anxious but Cathy is excited. William Hurley finds and tells the Doctor what's going on, telling him he had no idea this was the plan and he refuses to take part in the yeoman's riot quelling. Thomas Tyler notices the yeoman gathering and tries to convince Walton that it's too dangerous to use horses as the crowd is too packed but he does not care. Cathy and Nyssa notice the gathering cavalry and become scared. The cavalry draw swords and charge the crowd. Nyssa and Cathy attempt to avoid them. The Doctor tries to find Tegan who has gotten lost in the crowd. He finds Thomas Tyler and berates him for believing the lies of the yeoman cavalry, justifying their "actions" in the most ridiculous means. Roberts encounters Mr. Hurley who berates him for "letting" Cathy attend the protest and tells him to go find the baby he was talking about before it's too late. William and Tegan try to find Nyssa with no luck and William decides that they need to help people escape and head to one of the exits.

The Doctor and Thomas hear field guns and the Doctor, caught up in the moment, is angered that they would fire on their own civilians. He remarks that it's massacre like Waterloo. A second charge commences by the yeoman. Tegan and William find the Doctor and try to find Nyssa. Cathy is injured in the charge and her baby Peter is killed. Walton informs Mr. Hurley their job is done. Just then, Nyssa and the Doctor approach him and begins screaming at Hurley about how thanks to him Cathy has been trampled and injured and child is dead and he is to blame....

Part four
The Doctor demands a shocked Hurley to give them his horse. Tegan finds Nyssa and the Doctor who says they're going to try get Cathy to a hospital on horseback. The Doctor berates Hurley who dismisses him and says they deserved it and walks away, his job done. The Doctor tells Thomas to write down the events and have them published back in London. In the infirmary they discuss Cathy's recovery with the Sister on duty and when Nyssa remarks why there aren't more injured there, Tegan explains it's because they can't pay. William, guilt-stricken, says that Cathy's treatment will be covered under the Hurley's account and explains he's going back to the city to see if he can help anyone else. The Sister explains to Nyssa that even if their costs were covered the poor won't come because the infirmary would be forced to take their names, and their involvement in the event would implicate them, then leaves to go about her duties. Nyssa explains to Tegan that a great change seems to have come over William Hurley, and she suspects it's not because of the events of today, but that Cathy mentioned the two were childhood friends and grew up together and she strongly suspects that her dead child, Peter, is his son.

The Doctor and Thomas Tyler argue about how he will report the events and after a stalemate, the Doctor wishes him luck as he promises he will try to report what he can. Roberts arrives at the infirmary and bumps into William Hurley, who tells him he needs to settle "another" account, leaving a bewildered and confused Roberts. Roberts heads inside the infirmary and talks with Nyssa and Tegan, informing them of his recent encounter with William. Roberts takes over standing by for Cathy and Tegan and Nyssa run off to stop William Hurley, convinced he's going to murder his father. Mr. Hurley, distraught by his actions, talks and argues with Walton, explaining he is going home, fed up with the events and beginning to reconsider his stance on the recent events turning down the invitation to celebrate the "success" with the other cavalrymen. Tegan and Nyssa find the Doctor and explain they need to stop William before something else happens. William encounters Thomas on his way home, and Thomas invites himself on William's horse since he was heading there to pick up his luggage before heading back to London. He says he also wants to give Mr. Hurley his praise. They head off. Mr. Hurley arrives home distraught over the massacre and talks to Mrs. Hurley, explaining that Cathy's "brother" (unaware of the reality) was killed. Roberts talks with Cathy and she tearfully reveals his death, which Roberts was already aware. He reinforces that they need to keep their head down and she must stop participating in these events, but Cathy feels differently, saying that there are other "Peter"s in this world who need to be brought up in a better world and they need to fight for it. William and Thomas arrive home and he confronts his father by drawing his saber. The Doctor, Nyssa and Tegan arrive and see that the William Hurley has already arrived. They get inside just in time to stop William from stabbing his father. Thomas Tyler prepares to leave to report the falsified story and the Doctor tries to convince him otherwise, to no success. Nyssa, angered, reveals to Mr. and Mrs. Hurley that the child was William Hurley's and they were responsible for the baby and her, which William finally admits. Mr. Hurley breaks down but the three slip out before they are drawn into a familial conflict.

The Doctor explains to the two that this is a fixed point in time and its effects will ripple through history with lower class citizens fighting against the oppression by the rich to improve their living conditions. They arrive at the newly self-repaired TARDIS and an upset Nyssa goes inside without a word while Tegan and the Doctor reflect on the day's events.

Part one
The Doctor and Turlough arrive in an unmapped section of the Pandana system and the Doctor insists they be the "first" to explore. The Doctor spots irrigated land below the stormy mountain environment they've landed in, suggesting intelligent life and they decide to go there to get shelter from the storm. Meanwhile, Waywalker is guided by the voices of "Spring" and "Autumn". The voices lead her to a nest and tell her to open the ambricore (yellow fruit thing). The voices leave her and she calls out to them but gets no response... until the Doctor arrives just in time to save her from falling off the branch of the life tree where she obtained the fruit. Waywalker reveals she needs the ambricore for her "becoming". Just then they hear voices which are identified as entities called the "Hungerers", which begin to surround them, preparing to hunt them. The three try to head down after Waywalker asks the old ones (voices) for advice. The Doctor manages to cause a landslide to stop the creatures pursuing them, however, Waywalker ends up breaking her leg. Waywalker explains that she needs to get to the "Cavern of Becoming" before the ambricore goes off otherwise she will fail. The Doctor consents but convinces her to first let them gather some material to create a crutch support for her injured leg. They depart but just then Waywalker catches up and it is revealed she is quickly self-healing although they do not know why.

They ask her why she is doing this and she reveals that the "ritual of Becoming" is how they learn what they should "become" in their society and their identity is based upon they path they take. They travel to the Cave of Becoming.

When they arrive, Waywalker is instructed to break the ambricore and drink the fluid inside, which the Doctor realizes is the same as the "jelly" substance surrounding them, called the "Pathmaker". Waywalker walks into the large gelatinous mass and although Turlough tries to stop her, the Doctor prevents him and insists she be allowed to follow her own directions and they should not interfere with what the Doctor sees as a natural process. The Doctor surmises that the two have a symbiotic relation and that those that enter the Pathmaker are absorbed into the tree and are remade into ambricore. Turlough, against the Doctor's warnings, thinks something is wrong and dives in to save her. Once brought out, she reveals that the Pathmaker attacked her and rejected her because the voice of the elders did not leave her.

They begin to head back to the village and Waywalker explains that although she has failed she was able to keep her form and she seems to have gained new knowledge as she explains that the Doctor has revealed to her that the land is changing and new knowledge to survive may be required. The Doctor says they ought to be heading back to the TARDIS and when a protesting Turlough asks about the Hungerers, Waywalker reveals that they only detect/hunt Waywalkers, to Turlough's annoyance at not having told them before, and they then part ways.

The Doctor explains to Turlough the relation between the Pathmaker and the Waywalkers, but says that the changing sun causing the current cold climate is bothering him, and on top of this, he can't quite understand where the Hungerers fit into this ecosystem until he makes a startling realisation and runs to the village with a confused Turlough following in his wake.

Waywalker returns and reveals her failure to the villagers but explains that she has learned that their planet is changing and that they must find a new way to live as the old ways will not allow them to survive, however, uninterested, they remind her of the penalty. Just then, she begins to transform into a Waywalker and the Doctor, with Turlough in tow, explains that the failed Waywalkers become Hungerers. They arrive to see Waywalker transforming and the Doctor tries to save her using a psychic link but she says she is too far gone and it is too late to stop it. The Doctor offers to destroy the Pathmaker to end this but Turlough rebuts that this would end their entire civilization and the Doctor would have to take over the role of Pathmaker, make every decision for the society and rule over them and says that if he won't do this then their best option is just to go. Waywalker assures the Doctor that Pathmaker was not able to take all her thoughts and she may still be able to try and find a way to save their civilization. A distraught Doctor is finally persuaded by Turlough to leave and return to the TARDIS, expressing to Waywalker that he hopes she will find a way to save her civilization.

Part two
The Doctor misses and blames it on a fault with the weapon. The Duchess turns the situation into an advantage to gain sympathy. The Duchess' parents, Lord Crozion and Lady Crozion, discuss their disgust about her husband on their way over for the anniversary celebration while the Doctor and Nyssa go to "scout their area" attempting to find Tegan and Adric when they spot the Duchess. The Doctor proposes a plan to which she agrees to help him get his friends back and give her what she wants.

The Duchess meets with Tomek and explains that the Doctor's plan to get her gunned down will allow her to expose her husband and have him executed. Tomek is, however, suspicious of the Doctor's plan. Tegan and Adric are searching for the Duchess' would-be assassin, unaware that it was the Doctor who shot at them. The Duke and Duchess next participate in a horse race while the Doctor and Nyssa spot Tegan and Adric. The two encounter Amelia who tells them where to find "The Scorpion" and "Nyssa the Destroyer" and they head over there. They find them in the tower and as the Doctor and Nyssa prepare to enact their plan, the Duchess, having won the race, gives a speech but is murdered right in the middle before the Doctor's plan can be carried out...

Part three
The four confusedly speculate what has happened and try to figure out what to do next, thinking the Duchess has been murdered for real. They are caught but thanks to Nyssa's distraction, Tegan and Adric get away while Nyssa and the Doctor escape. The Duke explains to the Doctor and Nyssa what his plan is and what has happened. Tegan and Adric suddenly run into the Duchess who reveals the Doctor's plan worked and she knows who he really is, then tricks the pair and taunts them, attempting to have them arrested.

The Duchess' parents arrive and the Doctor tries to explain to them what happened, angering Lord Crozion, but the Doctor explains it was just a facade and she's still alive. The Duchess reveals herself to her parents but Lord Crozion is adamant and exclaims that they will still be invading to take back the dowry by force but is distracted to go collect his reward from the betting stakes. Just then he spots Tegan and Adric and puts them under arrest but the Doctor dissuades him and convinces the four to come with him to the throne room for an impromptu "marriage council" session but to no avail as Lord Crozion refuses to budge, believing his son-in-law the Duke to be worthless. Outside Tegan Nyssa and Adric discuss something that's been bothering them and realize that Amelia and Tomek may be behind all this. The Doctor speaks with Adric who reveals his suspicions and he talks with the Duchess and has her summon Tomek and the Duke summon Amelia. They discover that Tomek was using a hologram projector and was manipulating both sides, pretending to be both servants. Tomek/Amelia is arrested but Nyssa is still suspicious. She reminds the Doctor that a laser bolt still hit the podium when the Duchess was "murdered" and someone would still have had to fire it.

Just then a of Sting ship arrives overhead carrying real assassins, in this case the real Scorpion who threatens to kill them all unless the real Duchess is brought to her...

Part four
The Doctor tries to reason with the Scorpion but she sees through his lies. The Duchess stupidly reveals herself and a chase ensues while the Doctor tries to stall her by negotiating. He manages to get away and finds the others while the Scorpion captures Lord Crozion in a stasis field. The Doctor realises they need the help of Tomek/Amelia and in his interrogation of Amelia-Tomek, he eventually discovers that the two-timer is called Zaina and that she hired the Scorpion. After some coercing from the Doctor she agrees to help. They reconvene with the others and make a plan to stop the Scorpion.

The Doctor has the others distract the Scorpion while he rescues Lord Crozion. They eventually get the Scorpion to fall right into the Doctor's "trap". He takes the Duke's credcard and offers all the credits on it and in exchange the Scorpion will leave them all in peace. The Scorpion accepts but murders the Duchess in cold blood anyway to preserve her reputation as "no job goes unfulfilled". The Doctor "threatens" the Scorpion with a gun but she calls his bluff and turns away, only for the Doctor to pull the trigger... but it is revealed he modified it to simply put a stasis field around the Scorpion. After a difficult decision, the Doctor lets the Scorpion go despite her crimes, believing that handing her over to Lord Crozion would be no better as he insists he will kill her anyway. As she leaves, it is revealed that the Doctor, Zaina and Duke Sebastian tricked them all, using the holographic projector and other technologies. The Doctor reveals that it was Sebastian who bravely volunteered to pose (and save) his wife and Sebastian and Miranda reconcile and she forbids her father from invading Cardenas.

The four head back to the TARDIS and take-off. It is revealed that the Duke and Duchess end up in another argument before they even get to bed.

Part one
Leanne leads a guided tour of the catacombs. Initially successful, things spiral out of control when they hear strange sounds, and other frightening events begin to occur... when suddenly, Leanne hears the voice of the Doctor in her head.

The TARDIS crew land in the 17th century searching to help the senders of a distress call they intercepted. They split up and Adric and Nyssa are attacked by something unseen. Tegan and the Doctor discover a wall with blood markings on it and a pile of bones that shown sign of damage at the deepest molecular level. Adric, having fallen down the stairs in a panic, hears Nyssa call to him that she can't move as the creature seem to be holding on to her and instilling fear in her against her will. Adric tries to save her but also becomes stuck when the creature holds on to him. Tegan and the Doctor find the two frozen on the floor shivering, and prop them up, and they explain that the alien subdued them to lead the Doctor to it. They hear the creature's roar and run back to the TARDIS. Once inside, they realize the TARDIS is dead, and was trying to leave which is why it was making groaning noises before when they first arrived. The Doctor explains he can get it working again but they need to go back outside. They get a displacement generator working and he transports Nyssa, Tegan and Adric elsewhere. Just as he prepares to take on the creature, it is revealed Tegan didn't listen and left the circle for the generator at the last second to stay and help the Doctor, suspecting he didn't actually have a plan. He admits she's right. Leanna asks the Doctor if this is how he got stuck here, which he admits it is, but when she asks how he got out he reveals he never did and that he died here...

Part two
Nyssa lands in a village and the townfolk are convinced she's a witch and attempt to burn her, however, she is saved by Matthew Doyle the Reverend who takes her on horseback back to the vicarage. The Doctor and Tegan theorise how the creature managed to feed on the TARDIS, and the Doctor tries to help Tegan regain composure after she becomes tired, where the Doctor realizes the creature is feeding on her. He gets her to safety.

Adric, having landed in the same village at a different point in time, is put on trial for stealing some bread but is interrupted when he spots someone wearing a cloak, revealed to be a member of the Brotherhood of Sabaot. Matthew and Nyssa have a chat where she also learns about the Brotherhood of Sabaot and she learns she has been moved forward in time but not space and they plan to have Matthew go and visit their temple to see if there's anything they can learn. Tegan and the Doctor discuss about what they will do now and how they will escape. Matthew returns having been unsuccessful in talking with the brotherhood, and being egged by children. The more time she and Matthew spend together, more rumours, spread by Mrs. Stubbs, the Reverend's housekeeper at the vicarage, fly around the village that the Reverend has been bewitched by her. Matthew eventually reveals he has fallen in love with Nyssa but she turns down his advances due to the situation. Adric finds some people, having fled the trial, and asks them to tell the Doctor he's here, however, they are confused as they know no one of that name. Just then they are interrupted by cloaked men of the brotherhood and Adric tries talking to the cloaked men on behalf of the frightened villagers, while the events are recorded by a "journalist" on the scene while Adric is taken to his execution, his fate decided.

Nyssa and Reverend Matthew arrive at the church where he is to give a sermon, however, the villagers block him from entering until he recants and rids himself of Nyssa. Matthew attempts to defend her and her actions but the villagers are unconvinced and attempt to burn her. Matthew, in a change of heart, sides with the villagers (having had his heart broken by Nyssa) and they attempt to drown her in a river as the Brotherhood of Sabaoth encroach on her position. Meanwhile, Adric is placed in the gallows to be hanged, and the floor beneath him is dropped...

Part three
Leanne in the present explains that a boy named Derrick was hung from the gallows but mysteriously disappeared during the hanging and takes out a newspaper article and picture to show it, which the Doctor, in Leanne's head, tries to get her to give him a good look. They get into an argument and she tries to ignore him. He tries to convince her to explore the catacombs she gave a tour at earlier but instead continues her tour to show the "The Witch of the Lake". Meanwhile the Doctor and Tegan, in the past, continue to try and figure out what to do. Tegan, realizing a pick-axe would be helpful for a plan she has to tunnel out, goes looking for one inside the TARDIS but Sabaoth, projecting itself through the consumed TARDIS conscious, traps her inside the TARDIS and the Doctor tries to get inside but gets locked out. Tegan and the creature talk and it flings her mind forward in time as it drains her energy.

Doctor managed to get inside the TARDIS and finds Tegan collapsed on the floor and he finally confronts Sabaoth. In the present, he guides Leanne through the catacombs where they find his tomb, where his body is buried. However, he stops Leanne from breaking it open, explaining that currently he's both dead and alive, like a Schrodinger's ghost, as they neither know whether he is actually dead or alive (he's supposedly dead, but she can still hear his voice so he might be alive and neither believes in ghosts) and that observing the body of him actually being dead will create a fixed point in time, ensuring his death. The Doctor hopes to find a way to avoid this but Leanne is still considering breaking in if it means she will be rid of the voice in her head.

Tegan slowly reawakens and explains to the Doctor she went to the future and tried to warn them but she's not sure it worked. The last of her energy drains away and the two share a heart-felt moment before she passes on. The Doctor explains in the present to Leanne that he realizes now he's here to save her and they hear a voice calling from around them. The Brotherhood of Sabaoth surrounds them and encroaches on them, however, he tries to calm her down explaining that they're not real in the ordinary sense and are more like smoke and mirrors/illusions projected by Sabaoth and Leanne makes a run for it.

Some time ago, a boy and his girlfriend Katya play a game with a Ouija board and Katya becomes possessed, warning them that "Sabaoth is coming".

In the past the Doctor berates Sabaoth for killing Tegan and prepares to suffer his fate. Sabaoth continues to taunt the Doctor and slowly drain his energy while he continues walking around and staying active to not succumb to sleep and have the rest of his energy swiped by Sabaoth. The two continue to talk as the Doctor walks through the dead TARDIS and Sabaoth explains he plans to keep feeding on everything else by bringing himself into the universe from his spectral form.

In the present Leanne continues to run from the illusory cloaked men and the Doctor explains that she has traversed so much of the sites and crossed the many psychic barriers that Sabaoth is using her as an anchor. Meanwhile Katya is brought to an expert exorcist by her boyfriend and the exorcist goads her into a trance where she attempts to warn them that they must not let Sabaoth free. She cries that they must find the Doctor while the expert attempts to perform an exorcism, when suddenly the voice inhabiting Katya cries that they need to listen to her and that they don't understand as her name is Tegan Jovanka...

Part four
Leanne awakens the next morning to find that she has managed to escape the Brotherhood but the Doctor explains that she was supposed to and explains that Sabaoth planted a trigger in her mind and that going back into the catacombs will be catastrophic, however, she berates him, explaining she needs to pay her rent even if the world will end because of it (as he explained) and will be going back again to give a tour tonight. In the past, the Doctor builds a wall around himself and the dead TARDIS as he dies, explaining to Sabaoth that he cannot allow people to get their hands on the body of a dead Timelord. Leanne has lunch in a cafe and when she refuses to follow the Doctor's advice he begins to cause things in the cafe to shatter, break or rumble. Overwhelmed, Leanne tries to shut him down and accidentally manifests telekinetic powers, blowing out the city's electricity supply but at the very least she can no longer hear the voice of the Doctor in her head.

Later, Leanne gives a tour of the catacombs but begins hearing whispers and voices that she cannot block out. She explains that in the residence built on top of them, two students playing with a Ouija board in one apartment lead them to rediscover the catacombs running underneath the entire street (Katya and her boyfriend). She then leads them to the Temple of Sabaoth, and her patrons are revealed to be the Brotherhood of Sabaoth. As she prepares for her fate, the Doctor reveals himself just as Sabaoth appears.

The Doctor reveals he escaped death by going into a healing coma (an ability of Timelords) after he had sealed himself inside and projected himself into the head of the person that Sabaoth was using to be bring himself back into the world, Leanne. The Doctor and Leanne face Sabaoth together.

The Doctor awakens to discover himself in a fully operational and energized TARDIS which he used to go back and save Nyssa from being drowned and Adric from being hanged, as it turns out Leanne's telekinetic outburst was channeling Sabaoth's power and managed to send him back in time and restore some power to the TARDIS, allowing him to go save the others. In the present the Doctor, Nyssa, Adric and Tegan encourage Leanne to fight Sabaoth and she manages to suppress his return. They manage to vanquish him and the Doctor explains when he projected his mind into Leanne's he implanted a "virus" in it that she passed on to Sabaoth and coupled with having access to his powers as the two were linked, Sabaoth had set itself up for destruction.

The Doctor further explains that he ensured Nyssa and Adric were sent to points that would eventually lead to them becoming spots on her ghost walk and that he lied to Sabaoth about Tegan and put her into a cryo-pod so she could heal and it wouldn't feed on her, then woke her up "almost" immediately  after. They then dressed up in cloaks to blend in with the brotherhood that followed Leanne through her tour and that was when they appeared to help her defeat Sabaoth. He then explains that things should be back to normal from now with no more supernatural occurrences, which Leanne is thankful for, saying "she never really believed in ghosts".
