In the second episode of the six-part story "The Chase," the Doctor (William Hartnell), peering into the future, has learned of the mass-destruction plans of the mutant Daleks. He also knows that the villains intend to destroy the TARDIS and its crew. Feeling safer chasing after the Daleks than being chased by the mutants, the Doctor trails the enemy to the planet Aridius -- only to discover that he and his traveling companions have been trapped in the TARDIS and are unable to prevent the ensuing carnage. Written by Terry Nation, "The Death of Time" was originally telecast on May 29, 1965. ~ Hal Erickson, Rovi
