The Doctor wanders right into a Cyberman scheme to alter their own history. When he first encountered them, the Doctor engineered the destruction of the Cybermen’s home planet in order to save Earth. Now, the Cybermen – operating from their base on Telos – plan to divert the course of Halley’s Comet circa 1985, so Earth won’t be there to interfere in Cyber-history. Left behind after the attempted Dalek invasion, Lytton is up to no good on Earth, but his attempt to curry favor with the Cybermen in exchange for a ticket off of Earth turns into a deal with the devil that he can’t survive. And on Telos itself, a pair of renegade slave laborers tries to steal a Cyberman timeship, and the original inhabitants of Telos, who cannot survive in anything but sub-zero temperatures, enlist help in their own fight against the Cybermen.
