Faced with the prospect of discussing a tortured Cybermen story, we turned this into a Cybermen travelogue. "Attack" takes place just before Tenth Planet, and just after Tomb of the Cybermen. To make that make sense, we talk our way through ALL Cybermen stories. And find out what makes sense and what doesn't. 

The Doctor, Adric, Nyssa and Tegan land aboard a ship bound for Earth, but it carries representatives of ancient Earth cultures. And a megalomaniac with a soft spot for Adric. And Cato from the Pink Panther movies. We talk about this Silver Age of Doctor Who stories and enter 2 more Companion Files: Tegan and Nyssa.

The Fourth Doctor and Sarah Jane are joined in the TARDIS by UNIT's Medical Officer, Surg. Lieut. Harry Sullivan. Despite impressive credentials in science, Sullivan accidentally changes the ship's course and they land on a seemingly abandoned space station. It's classic 70s sci-fi -- Earth is uninhabitable. Samples of all organic life were sent into stasis in space until the Earth is safe for human life. But something got into the wiring . . . The Ark, and the Earth, need the Doctor, Sarah Jane and Harry to save it.
