Arachnids in the UK was the fourth episode of Series 11 of Doctor Who.

The Thirteenth Doctor finally returns Graham, Ryan and Yasmin to Sheffield, just half an hour after they had left. Notably, these new companions actively choose to travel with her at the end of this episode.

Some of the episode's plot curiously has some errors of logic in it. If the mutant spiders had been activate for some time, they should have been more public sightings of them, given the sheer size. Adding onto this is that if the spiders were able to infiltrate the hotel above the mine tunnels, there should have been more signs of their occupancy of the hotel than a single room covered in webbing.

It also marks the fourth time in Doctor Who history that spiders have been the threat of the episode. This role had previous been filled by the Eight Legs in Planet of the Spiders, the Racnoss in The Runaway Bride and the Spider germs in Kill the Moon.

It also marked the debut of the new version of the time vortex in-show. Unlike previous versions, where the TARDIS flies through one single pathway, this version shows multiple different paths.

Synopsis

The Thirteenth Doctor finally manages to bring her friends home, but with more time alone on the horizon, she soon discovers that something unnatural has happened to the eight-legged population of Sheffield. Why have they converged on an unopened hotel, and why is there a man going around like he owns the place?

Plot

The TARDIS flies through the vortex

The TARDIS flies through the time vortex at amazing speed; it exits out of one pathway and into an area of multiple different ones. It flies down one of the available paths. Inside the TARDIS, the ride is very bumpy as the Thirteenth Doctor works at sparking controls to get the TARDIS to cooperate. Graham wonders if the Doctor can actually control her time machine, to which she admits "very nearly" as the TARDIS tends to be mischievous.

The TARDIS materialises at an apartment complex in Sheffield, present day Earth. The Doctor pokes her head out of the TARDIS, happy to finally have gotten her companions back home. Yaz, Ryan and Graham exit after the Doctor, happy to be back. Yaz checks her phone, noting that she doesn't have any new messages. The Doctor tells her that its because the TARDIS has landed half an hour after they initially left. Yaz notes that they are right outside her apartment, with Ryan noting how weird it is as he and Graham only live a short distance away. Graham tells the Doctor that it's been and honour to meet her; a compliment she returns. Ryan wonders what the Doctor will do next, to which the Doctor says she'll resume traveling now that she has her TARDIS back.

Seeing how sad the Doctor is to part ways with them, Yaz asks if she wants to join her for tea. The Doctor's face brightens; she accepts the invitation, shutting the TARDIS doors. Yaz also invites Ryan and Graham, but Graham declines, deciding he wants to stop by home first. Ryan offers to come with him, but Graham kindly tells him that he needs some time to himself.

Graham stands outside his house, looking on, When he finally decides to enter, Graham looks around and imagines Grace playfully scolding him to remember where things are and when the trash is to be taken out. Graham tells his imaginary wife that he has so much to tell her about his travels.

Tea at the Khan's flat.

Back at Yaz's apartment complex, she, the Doctor and Ryan pass a woman in the hall. The woman is noticeably concerned and keeps trying to get the resident of a nearby flat to answer the door. The Doctor notices, but dismisses the thought. Yaz leads the Doctor and Ryan in her flat; she calls out to her family, telling them she brought friends. Yaz then mutters to the two that she hopes they're out. However, Yaz is out of luck; her father, Hakim, pops around from the kitchen, surprised that she's brought friends home for tea. He calls to Yaz's sister, Sonya, who walks out to meet them. Unlike Hakim, Sonya is skeptical that they are Yaz's friends, asking if she paid them to pretend to be her friends.

Elsewhere, at a lavish hotel. Businessman Jack Robertson is talking with his personal assistant Frankie Ellish in the hotel ballroom. She is protesting against an idea of his. Jack reminds her that they're family through Frankie marrying Jack's niece; that's why he trusts her to get things done. Jack's bodyguard Kevin enters, informing Jack that his private plane is waiting for him; however, Jack tells him that the plane will leave when he tells it to. Another woman walks into the room, much to Jack's surprise; it's Najia Khan, Yaz's mum. She tells Robertson that she can in early to do some prep work, being the manager. However, he impatiently fires her and walks out, after telling Frankie to deal with the problem.

Back at the Kahn's flat. Yaz, Sonya and Ryan sit at the table, while the Doctor looks around and marvels at the idea of flats. She thinks to herself that she could buy a flat, rambling on; she then asks Ryan if she was being weird. Once he confirms it, the Doctor says she's trying small talk, but is a bit nervous. She then notices a large pile of junk in the room, wondering if Hakim collects it like stamps. Much to Yaz's annoyance, Hakim says that its evidence as there has to be some kind of conspiracy. The Doctor smiles, loving a good conspiracy. Yaz tells her father that she asked the police to look into it. Sonya jokes that Yaz is married to her job, to which Yaz snidely remarks Sonya is unemployed.

Yaz gets a call from her mum, asking her to come pick her up; she also tells Yaz not to tell anyone as they'd only get worried. When asked about the call, Yaz lies that her mum just forgot something. Hakim tells her to hurry back as he'll be making pakora for tea. Yaz gives a frightened look, telling him not to as he's really bad at making it. As Yaz leaves, the Doctor thinks about how the sisters mock each other, reminiscing about having once had sisters. She then notices a piece of mail that states their neighbor has gotten a parcel for them by mistake. Hakim confirms it, stating that he's tried to get it, but hasn't been able to get an answer from his neighbor for days. Seeing a chance to pass the time, the Doctor offers to get the parcel "while [he] makes [his] terrible pakora."

Back at Graham's house, he is smelling Grace's jackets. His imaginary Grace chides him for doing something so silly as it won't change the fact she's gone. Graham hears a thud from the attic and heads up to check. He finds it filled with webs, and an unusually large shed spider skin on the floor.

At the hotel, Frankie has become fed up with working for Robertson and heads down to an underground area out of bounds to the public. However, she remains unaware of the large amount of webs in the basement corridor. Frankie uses her mobile phone to record a testimony to reveal a secret Robertson has been keeping from the public. However, she notices something further in that scares her; exclaiming in fear, Frankie is grabbed by something off-screen and pulled away. Her phone is left behind with the image of spider webs covering the cavern walls.

The Doctor discovers something is wrong.

At Yaz's flat, the Doctor and Ryan leave to collect the parcel. They find the woman from earlier still outside the flat, which is the very same one they need to visit. The woman introduces herself as Jade, explaining that one of her colleagues, Anna, hasn't been to work in a few days; she hasn't called in sick, so this is concerning. The Doctor asks if she's concerned about Anna enough to force her way in, to which Jade confirms. The Doctor helps by unlocking the door with the sonic. All three enter the flat, finding it covered in spider webs. The Doctor doubles checks how long its been since Jade heard from Anna, which is only a few days. Ryan notes that it looks like more than a few days from the lack of cleanliness.

They head down to the bedroom. They open the door to find a silhouette of a person of the bed. Jade calls out to Anna as Ryan pulls back the curtains. The lights reveals a dead Anna on her bed, covered in spider webs. A panicked Ryan joins the Doctor and Jade, asking if that spiders aren't supposed to do that. The Doctor tells him that's the wrong question; the question is where is the spider that did this? They carefully approach a wardrobe and open it; however, nothing is in it. The Doctor and Jade move for the door as Ryan checks under the bed. Something moves, startling him back to the door. A spider the size of a small dog crawls out. Jade and the Doctor note that its domestic, but way too big. They very carefully open the door and rush out. The Doctor orders Ryan to block the door while she gets some things. A very panicked Ryan tries calming himself, but finds the spider trying to reach under the door.

Jade joins the Doctor as Ryan yells for her to hurry. Jade realizes that the spider got in through the rubbish chute, wondering if they can force it back out through there. However, the Doctor is against the idea; it will be a bigger threat if released into the public. They have to trap it in here until they can devise a better way to deal with it. The Doctor takes some vinegar and garlic from the kitchen and spreads it on the floor, walls and ceiling in a square. She calls Ryan up and he rushes to join them. The Doctor explains that spiders smells through their feet; the strong smell of garlic and the acidity in the vinegar will dissuade the spider from following them. The spider approaches and just as the Doctor explained, the barrier works; she tells the spider to say put while she deals with this.

In the Kahns flat, Hakim and Sonya are waiting for Yaz, the Doctor and Ryan to return. Hakim notes its taking them a long time to retrieve a parcel.

Back to Yaz. She's driven up to hotel to pick up her mum, meeting her in the lobby. She warmly hugs Najia who is curious as her daughter only saw her earlier that morning. Yaz notes the nice looking hotel and is impressed her mum works here, but Najia tells her that she just got fired. When Yaz asks who fired her, Robertson enters with his bodyguard Kevin hostility pointing a gun at both Kahns. Robertson states that he fired Najia, but she is still there (now trespassing) and called in another person. Najia tells the arrogant man that she called her daughter for a ride home. However, Yaz demands to know why. Mistaking her for a teenager, Robertson says she should be in school and that if he hadn't fired Najia, he would have ten minutes ago when he saw the rooms. Both Yaz and Najia demand to know what he means.

The Doctor, Ryan and Jade rush out of the flat and lock the door behind them. Graham joins them, telling the Doctor about what he found in his house. Catching her breath, the Doctor notes Jade wasn't surprised by the spider webs in the flat and demands to know what she knows. Jade explains that this wasn't the first incident; something is wrong with the spiders in Sheffield. She then explains that she's a scientist that works with arthropods and arachnids. As they walk off, Graham hands Ryan a letter addressed to him from his father that he found at the house; Ryan simply pockets it.

The Doctor draws a map marking the spider's location.

They head to Jade's lab, where Jade explains her lab has been working on enlarging spiders to harvest their web as its more durable than Kevlar. Ryan tells Jade that it's not making him like them any more. The Doctor tells Ryan that Jade is right about webbing; if it was round thick as a pencil it can stop a plane. Graham wonders if the Doctor is serious about that; she tells him that she's had to deal with it with Amelia Earhart. Returning to the problem at hand, the Doctor asks Jade to clarify what she means by something being wrong with the spiders. Jade pulls out a map, which she has marked for unusual activity; species not supposed to be out during this time of the year, large numbers and massive web-building. What's been perplexing her is whether this all this out anger, confusion or fear? However, the Doctor instead realizes the spiders are sending a message, grabbing a marker and connecting the dots on the map. It forms a webs with an empty area in the middle: Robertson's hotel.

At the hotel, Robertson shows Najia and Yaz a room covered in webs, which he blames on her for poor house keeping. He fires her again, noting it's time for his scheduled bathroom break; he and Kevin head for the next room, warning the Kahns to be gone by the time he's done. Yaz hears a strange sound coming from the wall and listens, unaware a large spider is on the other side. Najia gets a call, telling Yaz its a doctor; Yaz takes the call, knowing its the Doctor. The Doctor asks Yaz to let her group in the hotel.

Kevin fires at the spider

In the bathroom, Robertson is washing up. He hears an odd sound coming from the tub, but dismisses it. Suddenly, the tub starts cracking. The tub "explodes" with Robertson backing up to the door; he yells in panic as a giant spider crawls out. Kevin opens the door, gun ready; Robertson shuts him in with it. In the lobby, the Doctor greets Najia with a hug; she tells her that she made an awesome human. Everyone hears gunshots, immediately racing to find the source. Robertson asks Kevin through the door if he killed the spider; he cracks open the door to see the spider on top of Kevin and silently closes the door in terror. He then realizes in horror that his phone was in there; unfortunately, Kevin grabs it in his futile attempts to escape as the spider drags him back into the hole.

Robertson runs back into the hall, where the Doctor uses the psychic paper to pass herself off as a "Crisis Investigator". She asks for a full explanation about what he just saw; Robertson recaps very clearly what happened. The Doctor takes Yaz with her to investigate. Robertson remains with the group, being recognized by Graham and Ryan. In the bathroom, the Doctor decides to poke her head down the hole to see what's down there. Hearing a skittering, she turns to see a spider and rushes back out of the hole; she pulls Yaz with her back to safety. The Doctor tells everyone they need to get somewhere bright and not so abandoned for some safety against the spiders. However, Robertson and Ryan are for leaving altogether. Everyone agrees and starts running. Robertson asks Graham who they are, being told that "run now, ask questions later" is the best way to stay alive. Everyone reaches the lobby, only to find that the spiders have webbed up the entrance to trap them. Robertson tries passing this off as some kind of Eco-protest against his hotel, but isn't fooling himself. Realizing the spiders intend to trap them as prey, the Doctor asks Najia where the brightest room is in the hotel - the kitchen.

The Doctor takes charge

Everyone races into the kitchen, with the Doctor noting they need to find a way to deal with the spiders. Robertson starts to interrupt, but then realizes that the Doctor just said that there's more than one giant spider on the loose in the hotel. The Doctor initially mistakes Robertson for Ed Sheeran, finding out Robertson is just another greedy, egocentric businessman. Jade adds Robertson is even planning to run for President of the United States just because he hates Donald Trump; Robertson is notably disturbed by the use of the name. After her companions firmly say she's in charge, the Doctor begins thinking, asking for facts to help solve the problem. Najia remembers that Frankie was telling Robertson about something he wanted taken care of; Robertson reveals that the hotel is built over an old mine. They have to find out if the hotel is a target or the spiders' base. The Doctor tells everyone that they need to find out what Roberson is hiding and to capture a spider.

Robertson leads the Doctor, Yaz, Najia and Jade to the basement corridor. They arrive at the door Frankie entered, but its locked; however, that's not a problem for the Doctor. The Doctor opens the lock with the sonic and everyone follows her inside. Yaz finds a fuse box and gets the power back on, revealing a tunnel covered in webs. Robertson reveals that this used to be a mine, but he bought the land and re-purposed it into a hotel. They come across two cocoons, which contain the bodies of Frankie and Kevin. The Doctor smells something horrid further in, finding cavernous area of the mine has been used as a landfill. Though he attempts to deny having any knowledge of this, Robertson relents and reveals that his waste disposal company JLR Disposal cut corners to make their bottoms lines. The Doctor notes that this is effectively toxin waste, building up and getting more toxic; the smell is even reaching Park Hill flats, which is what make Rakim so suspicious. Jade then reveals that JLR takes their lab waste; she concludes that one of the presumed dead spiders was actually barely alive and ended up in the toxic waste. The Doctor realizes that it's augmented lifespan was mutated by the waste, causing it to grow to colossal size.

In the hotel hallway, Graham is talking to himself. It draws a spider, which slowly approaches him. However, before it can do anything, Ryan slams a pot over it and Graham slips a lid underneath to trap it. Ryan looks behind Graham in fear, telling him to run. They proceed to run back to the kitchen as a horde of spiders crawl after them. Back in the kitchen, Jade examines the specimen, wondering if its the biggest one. Ryan tells her that there's no way that they're going back out there to find another one. Jade hesitantly tells him that it's most likely the case. The Doctor asks to be shown a map of the hotel.

The Mother Spider in the Ballroom

Graham and Ryan head to the ballroom, where Ryan reveals that he read the letter; his father wants him to come live with him, since Graham isn't his biological family. Ryan says he's not for it, making Graham happy. However, both realize that they didn't check the ceiling when they walked in. They shine their torches up and find an ENORMOUS spider on the ceiling. As they turn and run, it lands with a loud thud. It chases after them, but they manage to slam the doors in its face. At the same time, the Doctor is examining a map of the hotel to find a way to trap the spiders. Robertson reveals that his panic room isn't on the map, so its not accurate. Najia asks Yaz to explain who the Doctor is to her, but is ignored. Pestered, Yaz tells her mother that she owes the Doctor her life on more than a few occasions.

Everyone meets back in the kitchen. The Doctor wonders what they found. Graham explains that the spider was the size of a large van; the Doctor concludes its the mother spider, and the rest are its babies. The Doctor then realizes that the reason that the spiders have sudden appeared is because every living thing in the universe has the instinct to come back home. She tells Jade that Anna likely had the pheromones on her from working at the lab, accidentally calling to a spider that left to hunt for food. The Doctor asks to be shown Robertson's panic room.

Robertson reveals his panic room has six months worth of supplies inside, along with guns. Ryan tells him the Doctor is against guns. Robertson wonders what's wrong with them, as guns are a "civilized" way to deal with a threat. The Doctor says they are going to lure the spiders with the promise of food and lock them inside, allowing them to die off in peace. As spiders sense food through vibrations, the Doctor asks if anyone has any ideas. Ryan complies, playing Stormzy's song "Know Me From" over the speakers in the hotel. The spiders head for the source, all the while, with Ryan and Yaz by the gate to the panic room area, and Robertson by the actual door.

Robertson coldly defends his actions.

Once the spiders are secured, everyone heads to the spa, where the Doctor tells them to stock up on essential oils. She tells them to meet her in the ballroom. They enter, armed with spraying packs; the Doctor explains that its diluted strong-smelling oils, which they can hopefully use to herd the spider outside. However, Jade stops them; she notes the mother spider has gotten too big to breath efficiently. The Doctor apologies to the spider for its fate, just as Robertson enters holding a gun; despite the Doctor's pleas, he shoots it. The spider roars in pain, falling over dead. Angered by his actions, the Doctor tells Robertson that the spider wasn't a threat; it was already dying. Robertson passes it off as a mercy-killing, telling the Doctor that he doesn't need her permission. He states that his kind of thinking will get him into the White House one day. As Robertson walks off, Ryan can only quip "God help us".

That night, Ryan heads out to say good-bye to the Doctor. Graham lingers, as his imaginary Grace tells him to get going. In her flat, Yaz listens to her family bicker; her mother telling her father to get rid of the trash. Hearing they're out of bread, Yaz offers to go get some. Najia thanks her, telling Yaz that she better tell her about who the Doctor is when she gets back. Yaz smiles, stating she will when she gets back.

Outside the TARDIS, Yaz, Ryan and Graham have gathered. Graham knocks on the TARDIS and the doors open on their own. They walk inside, finding the Doctor at the console. She asks if this is really goodbye. However, Graham states that he's changed his mind, as he wants to see more of the universe to help him move past his grief. Ryan doesn't want to go back to his job, having found life in the TARDIS to be more fulfilling. Yaz states that traveling with the Doctor is better than being driven insane by her family. Happy to not have to travel alone or find a new companion, the Doctor welcomes her 'fam' back to the TARDIS However, finding that it doesn't sound right, the Doctor asks if Team TARDIS sounds better; they agree. Together, they pull the lever to start their new adventures through time and space.
