In the conclusion of the six-part story "The Power of the Daleks," the Earth colony on Vulcan braces itself against the final assault of the dreaded mutant Daleks. Also pitching in are the "new" Doctor Who (Patrick Troughton) and his recently reunited companions, Polly (Annika Wills) and Ben (Michael Craze). But their combined efforts may well come to naught, thanks to a traitor in their midst. Written by David Whitaker and (uncredited) Dennis Spooner, "The Power of the Daleks, Episode 6" first aired on December 10, 1966; at present, this episode is believed to be lost.
