The Doctor and Adric are taken prisoner aboard the freighter after they've discovered one of the crewmen dead. Captain Briggs is upset at the delay the disappearance of three crew members has caused but the Doctor denies having anything to do with that. Meanwhile, the Cyber leader activates the Cybermen they've placed in the ship's hold and sets off to take control of the ship. Unbeknown to anyone, a member of the crew is assisting the Cybermen in their quest but the Doctor finds a way to hold them off, at least temporarily.
