Mia Farrow stars as Rosemary, a young wife whose husband, an actor, falls in with a group of Satanists. When Rosemary becomes pregnant, she begins to suspect that she may be carrying the child of the Devil. Director Roman Polanski caused controversy by giving a real life Satanist a part in the film's rape scene, and the self same man became implicated in the Manson murders which killed his wife Sharon Tate a year later.
