Revenge of the Cybermen - Part Two
The Doctor escapes from Kellman's quarters. He rushes to save Sarah who was just bitten by a Cybermat. The Doctor kills the Cybermat but is too late to prevent Sarah from getting infected. He sends Harry with Sarah, who is unconscious, by tranmat beam to Voga. There is a piece missing from the tranmat device but the Doctor rigs it together good enough to get it to work once.
Stevenson and Lester hunt and capture Kellman. The Doctor asks him for the missing piece to the transmat beam. Kellman refuses to talk until the Doctor threatens to sick a Cybermat on him. The Doctor puts the transmat beam back together but when he activates it no one materializes.
Sarah recovers as soon as she and Harry materialize on Voga. Something about the act of tranmitting her from Nerva to Voga cured her. Sarah and Harry quickly get caught up in an internal squabble between warring factions on Voga.
The Cybermen dock with Nerva. They kill the Doctor, Stevenson, and Lester when they try to fight back against the alien invaders.
