In the second episode of the six-part story "The Power of the Daleks," the Doctor (Patrick Troughton) and his companions arrive at the earth colony at Vulcan, where a trio of Daleks repose in a state of suspended animation. The thick-eared colonists, convinced that the Daleks can be trusted, prepare to thaw out the bodies -- an act of largesse that the Doctor must prevent at all costs. Written by David Whitaker and (uncredited) Dennis Spooner, "The Power of the Daleks, Episode 2" first aired on November 11 1966; this episode is believed to be lost. ~ Hal Erickson, Rovi
