In the conclusion of the three-part story "Survival," the Doctor (Sylvester McCoy), Ace (Sophie Aldred), and Sgt. Paterson (Julian Holloway) have been whisked away to the Hunting World, where they find themselves the quarry of the dreaded Cheetah People. Pulling the strings of this situation is the Doctor's perennial nemesis, the Master (Anthony Ainley), who has aligned himself with the Cheetah People -- an alliance that may have devastating consequences on everyone in the universe, including the Master. It is up to the Doctor to set things right by summoning what a psychiatrist might refer to as "The Inner Beast." Written by Rona Munro, "Survival, Episode 3" was originally seen on December 19, 1989, at which point the 26-year-old series Doctor Who went into mothballs until the 30th anniversary special four years later. ~ Hal Erickson, Rovi
