The Doctor, Mark and Anya head for an SSS space-station searching for the missing temporal scientist, Arborecc. But the officer in charge denies all knowledge of his presence and demands their departure.

Unwilling to leave so easily, the group split up to investigate... and uncover a heinous plot involving the Doctor’s oldest foes. Or do they?
