A murderous baboon escapes from a laboratory and roams the research building, and begins to kill some teenagers who are also in the building playing a Dungeons-and-Dragons type game.

Angela (Amanda Wyss) is a sensitive teenager and her fanatically religious father has forced her to dress and work like a boy in his gas station. When Beth (Mary Crosby), who has a split personality, escapes from the sanitarium, she meets Angela. Beth tempts Angela to be a real girl by wearing Angela mother's clothes. Then both become a lethal combination.
