Cobwebs (audio story)

Cobwebs was the one hundred and thirty-sixth monthly Doctor Who audio story produced by Big Finish Productions. Released in 2010, it began the first season of Fifth Doctor stories for that year. It was the first new story to feature stars Peter Davison, Sarah Sutton, Janet Fielding and Mark Strickson since the television story Terminus in 1983, thus beginning a "series" of 12 audio dramas for that TARDIS team across four years, finally reaching a conclusion with the audio story Prisoners of Fate in 2013.

Publisher's summary
"You know what cobwebs mean. Spiders..."

In search of a cure for a sickness that's so far claimed six billion lives, scientist Nyssa arrives at an abandoned gene-tech facility on the toxic planet Helheim. "Hellhole", more like.

Nyssa's not alone. The TARDIS has also been drawn to the Helheim base — and in its cobweb-coated corridors, she soon runs into the Doctor, Tegan and Turlough, her travelling companions of half a century past. But who, or what, has engineered this strange reunion? The Black Guardian, perhaps?

The answer's here, in the dark. With the Cractids. In the cobwebs.

Part One
Tegan and the Doctor are embroiled in an argument about Turlough. Tegan insists that he shouldn't be trusted whilst the Doctor says that he chose the right side when he was called upon. When Turlough enters Tegan storms off.

Meanwhile the Doctor's previous companion Nyssa is hovering above the planet Helheim with her paranoid android Loki. They are there to source out the abandoned research centre on that planet. They pick up a radio distress signal from 40 years previously warning that the planet has gone into quarantine. Despite his protestations Nyssa send Loki to investigate.

Back in the TARDIS, Turlough apologises to Tegan and tells her that he wants to be returned to his home. Tegan seemingly relents but as they begin to land the TARDIS goes into free fall. As they go to the control room they find the Doctor attempting a forced landing, while the Doctor does this Tegan wonders if this is a Black Guardian trap but the Doctor refutes this.

Loki finds no signs of life or any harmful pathogens. Nyssa joins him in the base. Loki informs Nyssa that there are traces of a series of subterranean ruins underneath the base - Nyssa says they will investigate. Nyssa seems concerned about the amount of cobwebs in the base but her fears are allayed when they discover robot maintenance spiders. Nyssa finds the power generators and manages to switch the lights on. When she does Nyssa sees a number of large crab like creatures approaching her. She begins to panic and implores Loki to neutralise them, however Loki cannot see or sense them. Nyssa screams in panic as the animals crawl on to her.

The Doctor, Tegan and Turlough emerge in the middle of a base. The first thing the Doctor notices is the preponderance of cobwebs but with no sign of dust that are dating them. His concern is allayed when he sees one of the robot spiders on Tegan. The trio begin to investigate the base. They note that the quarters see no sign of any personal affects and imply a quick escape. They hear a noise that draws them into the next room. Loki approaches them threatening them to remain still. Even though they do he fires a stunning beam at the Doctor. Nyssa emerges from the darkness and calls Loki off. The Doctor and Tegan seem surprised to see their old friend there. They discover that the events of their parting, a mere two days ago for the Doctor and Tegan, were fifty years previous on Nyssa's timeline. She explains that she is here to try and find a cure for the deadly Richter's Syndrome that is sweeping through the universe and has killed six billion people. The people at this base were supposed to be sourcing the cure but communications dropped. The group split up. The Doctor and Turlough go to explore the ancient ruins whilst Nyssa and Tegan with Loki go to access the computer database. As soon as they access the main deck of the base Loki warns that he feels a presence all around them. The voice of the computer greets the humans stating that he knew they'd return.

Down in the ruins the Doctor hypothesises that this civilisation must have had great technological power if it was their infrastructures that dragged the TARDIS off course. As they Turlough asks about how long the Doctor knew he was working for the Black Guardian and if he trusts him, which the Doctor replies that he trusts Turlough as Turlough trusts him. Turlough then sees a figure approaching them - the Doctor cannot see anything. Turlough screams with panic as he is 'fired at'.

The computer system refers to himself as EDGAR and says that the travelers have been here before. Nyssa wonders if this may have happened later in their time line but earlier in the timeline on Helheim. The computer begs the humans to "pity him".

The Doctor rushes over to Turlough who seemingly just collapsed. Turlough informs him of what happened. When the Doctor tries to put it down to hallucinations, Turlough says that he actually felt the rays of the gun enter his body. The Doctor points out there is not a mark on him. The Doctor and Turlough go and join their friends on deck. When Turlough recounts his story Nyssa states that she had a similar experience. The Doctor states this to be a telepathic memory projection coming from the previous crew. Tegan points out these must be the last memory's of the crew. When the computer speaks to the Doctor he decodes that EDGAR must stand for Ersphile Data Gatherer and Research. The Doctor asks EDGAR to show him the crew. EDGAR projects the three original member of the crew. Tegan asks of there have been any other humans on the base. EDGAR shows footage of the travelers - the Doctor immediately stops this saying that they cannot know of their own future. Tegan worried and panicked asks EDGAR where the crew are currently. EDGAR answers that they are in the medical bay.

Despite the protestations of the Doctor, Tegan marches to the medical bay where she orders Loki to open the doors which have been locked from the inside. When they enter they see four decomposed bodies cocooned on the beds. The bodies are wearing exactly the same clothes of the Doctor and his companions are at this moment and the travelers surmise that these are their remains.

Part Two
Tegan refuses to believe that the remains are them and that whoever dragged them there also put the remains there. The travelers argue about if the remains are them so they ask Loki to scan them, when he does he finds the remains are the travelers but Tegan still refuses to believe him so the Doctor and Nyssa take samples to perform tests.

While the results are coming in Turlough hypothesizes that the base was not only working on the virus. The tests results show that the skeletons are genetically identical and were also the same age as the travelers currently are when they died. The Doctor also refutes the ideas that the remains are clones or from an alternative timeline. However Tegan starts to believe that the remains are them and storms off scared.

The Doctor follows after her and she tells him that they should leave and go somewhere else so that the future won't happen. When the Doctor tries to explain why this can't happen because it would cause a paradox, but Tegan is too scared to listen to him and says she won't let the future happen. EDGAR overhears this conversation and won't let them leave him alone again.

Meanwhile, Nyssa investigates the data logs while Loki asks her to leave. Turlough mentions they shouldn't be looking into what happened but Nyssa says her mission to find the cure is too important. They find a recording of Cardell saying they found a cure for Richter's but the message is incomplete and all details of how the cure was found are deleted. Nyssa wants Loki to link with EDGAR but he has returned to Nyssa's ship as he was scared.

The Doctor is still trying to talk to Tegan about their future, when a door appears only the Doctor can't see it. The door starts to open and Tegan starts to have difficulty breathing, the Doctor realizes this is another memory projection of one of the crews final moments and gets EDGAR to stop it. The Doctor wonders why EDGAR has been programmed to show these specific memories.

Nyssa and Turlough go back to Nyssa's ship and find Loki. He says that EDGAR is going to kill them but can't explain why. They spot the robot spiders in Nyssa's ship having come in through the fuel ducts and are sabotaging the ship. The hyper ship drives start to fire and they evacuate as the ship will now blow up as its on the ground. EDGAR is pleased as they can no longer leave.

Tegan is recovering from the hallucination when they hear the explosion. The travelers reunite and theorize that EDGAR is behind this to ensure they can't leave. EDGAR says he is trying to save them from their fate and so he isn't left alone. He wants to take his past away. He knows they can time travel and wants them to go back and stop the crew being killed.

Tegan wonders where the crews bodies are, and if the remains are their future then where is their TARDIS. Turlough thinks the alien ruins are involved, so the Doctor says they must now go back in time to find out what happened. Tegan and Turlough are against this as they want to prevent their deaths, but the Doctor and Nyssa say they must. EDGAR then commences a self destruct option, but Loki has vanished. The Doctor sends Tegan and Turlough to the TARDIS while he and Nyssa go to look for Loki and find out he's in the control room.

Loki is found in the control room and the Doctor tries to stop the self destruct but EDGAR commits suicide so that he can final die and the countdown cannot be stopped. With nothing else to do they head back to the TARDIS. Back at the TARDIS they are about to take off but Loki is still outside, luckily he arrives in the last second and they escape the explosion.

40 years in the past Cardell is saving a memory record when the TARDIS appears. She calls Valis and Bragg and gets them to go to where it has landed.Inside the TARDIS they remark on how new the base looks and notice the crew don't appear to be pleased to see them. Back outside the crew are wondering what the TARDIS is, wondering if it is enemy agents and why its here.

In the TARDIS, Tegan wants to warn the crew, but the Doctor says they can't as its against the rules of time travel. Nyssa tries to stand up for the Doctor, but Tegan is too cross and thinks the Doctor is wrong. The Doctor says none of them have to come with him outside and Tegan and Turlough choose not too, but Nyssa says her mission comes first and her and Loki will go with him.

When they go outside they are held at gunpoint and they convince the crew that they were sent by the company to inspect the progress they have made on Richter's syndrome. Valis says they have not made much and that they are still a way of a cure, much to Nyssa's horror. Cardell and Valis say they will show them their research and Valis says her and Bragg will kill them if they turn out to be spies.

Inside the TARDIS, Tegan and Turlough watch all of this and Tegan remarks that they are safe unlike the Doctor and Nyssa. Turlough wonders if staying in the TARDIS is the action that will lead them to end up dead in the future, and suggests they should try and warn the crew as it might change their own futures as well. Tegan also agrees they should and they both leave the TARDIS.

In the laboratory, Nyssa recognizes the crab like creatures from the memory projection in cages and Cardell tells her they are called Cractids. They are the only creatures with an immunity to Richter's syndrome and they have been trying to replicate their immunity in humans by infecting them. Nyssa suggests making the Cractid immunity part of the human immune system instead of the other way around.

Bragg checks up on the Doctor and Nyssa and finds out that they have been lying and so plans to kill them, he then locates Tegan and Turlough leaving the TARDIS. He then finds Loki and destroys him when Loki tries to stop him from killing the travelers. Back in the laboratory, Nyssa asks Valis what she used to do, but she tells her that the entire crew had there memories wiped before starting the mission and they get them back after the end of the mission. Cardell is suspicious about why the Doctor does not know this considering he's from the company but he pretends to have forgotten.

Tegan and Turlough are trying to find a member of the crew when Bragg finds them and holds them at gunpoint. They try to warn him about the crew's forthcoming deaths but he believes they are threatening him. Valis is injecting the modified cure into a Cractid, when Bragg brings Tegan and Turlough in, he tells Cardell about the travelers lies, and the travelers are taken to the medical bay. There they are strapped to the beds and are to be given lethal injections and the Doctor points out this is how they end up dead in the future.
