1. Klein's Story by John Ainsworth and Lee Mansfield (1 part)
Elizabeth Klein is an anomaly. A renegade from an alternate future in which the Nazis won World War II. In an attempt to get to know his latest companion, the Doctor invites Klein to tell him how exactly she came to be in possession of his TARDIS and of the events that led to her trip into the past to Colditz Castle.

2. Survival of the Fittest by Jonathan Clements (3 parts)
On a distant world, the Doctor and Klein discover that the insect-like race that they have come to know as the Vrill have been all but wiped out by the mysterious and terrifying Winterlack. Discovering the true nature of the Winterlack, Klein is cast out of the Vrill nest into the jungle beyond. There, she is forced to confront the Winterlack threat alone.

In the Vrill nest, the Doctor desperately searches for a way to save the Vrill from extinction. But the odds are against him, and time is running out...
