Raising Cain is a 1992 American psychological horror thriller film written and directed by Brian De Palma, and starring John Lithgow, Lolita Davidovich and Steven Bauer. Respected child psychologist Dr. Carter Nix's wife, Jenny, becomes concerned that he is obsessively studying their daughter Amy; he regards her like a scientist tracking the development of his creation. However, Carter himself suffers from multiple personality disorder, as his alternate personalities include violent petty criminal Cain, shy 7-year-old boy Josh, and middle-aged nanny Margo who protects the others at all costs. Carter and Cain are killing young mothers to procure their children, apparently for experiments performed by Carter's father, a child psychologist who lost his license years earlier after performing unethical experiments on children.
