A dramatisation featuring Patrick Troughton and Fraser Hines
The Tardis narrowly avoids becoming engulfed in a web-like substance in space. Arriving in the London Underground railway system, the Travellers discover that the tunnels they find are also overrun with web. They find that it is the web from the Great Intelligence's robot Yeti.
The time travellers learn that this crisis was precipitated when Professor Travers, whom they first met some forty years earlier, accidentally caused a Yeti to be reactivated, opening the way for the Intelligence to make another invasion attempt.
The Doctor and his team work alongside army forces - led initially by Captain Knight and then by Colonel Lethbridge-Stewart - as they battle against the alien menace, hampered by the fact that one of their team has fallen under the Intelligence's influence and is a traitor in their midst. The Intelligence's ultimate aim is to drain the Doctor's mind. Will the Doctor survive the Intelligence's deadly plan?
The second doctor, Patrick Troughton, takes on The Great Intelligence in this exclusive recording taken from a lost television episode, with narration links from Fraser Hines.
