Plot
A cloaked figure studies images of the Doctor in solitude. He reflects on the legacy of the Doctor, as well as what he is capable of. He then notes that the Doctor has always had friends, and that he will have to change that...

The Doctor arrives at the Royal College of Surgeons in London, England in the year 1868. The First Doctor, Ian, Barbara, and Vicki step out. The group has arrived to meet Thomas Huxley, a friend of the Doctor's and evolution supporter. After attending his lecture, they meet with Thomas. Huxley is happy to see the group, but is soon called away. Thomas explains that he and some of his pupils must go searching the London Underground for a group of missing students. The Doctor convinces him to let them come along. Some time later, the Doctor, Ian, Barbara, and Vicki arrive at the entrance to the London Undergrounds to help look for the students. They find a fresh trail of footprints leading to a mysterious passage, covered in webs. Vicki begins suffering from headaches, something which last happened to her on Vortis. Barbara reminds her that they are far away from Vortis and that there can't be a connection. Suddenly, the group finds themselves surrounded by Zarbi.

The group tries to fight them off, but the Doctor suggests against it, saying that going with them is the only way to find the missing students. Ian, Huxley, and the Doctor are split away from the rest of the group, who are given gold mind-control bracelets to wear. At the Doctor's suggestion, Ian and Huxley fight off the Zarbi and the trio escape.

After searching the tunnels, the Doctor finds the Animus, who says a seed of it remained despite the destruction. It has reformed itself on Earth to get revenge on the Doctor. The Animus plans to take over Earth with an army of Zarbi drones, but before he can enact his plan he is hit by a train piloted by Ian. The Doctor uses a portal to send the Zarbi home. After some debate, the Doctor convinces Huxley to keep quiet about what he has seen. Huxley leaves, noting that he hates leaving the Doctor alone. The Doctor notes that the Animus could not have reformed on its own, and that the portal used to bring it here was beyond its technological abilities. The Doctor suggests further investigation to his companions, but is shocked to find them missing.
