Fourth Doctor 1.1: Destination Nerva

After saying their goodbyes to Professor Litefoot and Henry Gordon Jago, the Doctor and Leela respond to an alien distress call beamed direct from Victorian England. It is the beginning of a journey that will take them to the newly built Space Dock Nerva... where a long overdue homecoming is expected.

A homecoming that could bring about the end of the human race.
