The Doctor visits his old Time Lord friend Chronotis in Cambridge, 1979.

Filming for this story was never finished, and in this version the unfilmed material is completed via animation.

Bill Baggs first met JNT as a fan at the BBC Dr Who Production Office in the 80's. He later worked with JNT on various projects. Bill conducted this interview as part of the BBV dvd '30 Years of Time Travel & Beyond' produced in 1995. In the recording sequence of filming, Bill conducted this interview last in order to give John the opportunity to respond to criticisms from other contributors. The cafe where it was filmed was local to JNT in Saltdean, near Brighton where he was a regular visitor. When Bill first approached Jon about the documentary, John was initially resistant to take part, asking why he'd been left until last. However, once Bill explained the logic of 'save the best 'til last' John agreed.

The colonists refuse to heed the Doctor's dire warnings that the Daleks are dangerous.

Doctor Who and his companions are hurled into the future and make a horrifying discovery: the Daleks have conquered Earth! The metal fiends have devastated entire continents and turned the survivors into Robomen.
