"The Garden of Fear" adapted from a story by Robert E. Howard.
Conan and Jenna meet a group of hill tribesmen in a hidden valley, and are accepted there, though they cannot communicate. Things are well until a winged demon takes Jenna in the night to a tower at the far end of the valley. Conan is on his own to rescue her. He finds the occupant of the tower of cunning intelligence, and that the tower itself is surrounded by flesh-eating vegetation. He comes to understand that he faces an ancient and godlike being who is toying with him.
