Writer-director Brian de Palma "maintains a fever pitch from start to finish" (Leonard Maltin) with this "steamily libidinous and extremely bloody thriller" (Newsweek)! Starring Michael Caine, Angie Dickinson and Nancy Allen (in a Golden Globe-nominated performance), this taut psycho-sexual chiller is a razor-sharp tale of passion, madness and murder that's as "scary as the devil [with] suspense to spare" (Playboy)! Fashionable Manhattan therapist Dr. Robert Elliott (Caine) faces the most terrifying moment of his life, when a psychotic killer begins attacking the women (Dickinson and Allen) in his life with a straight razor stolen from his office. Desperate to find the murderer before anyone else is hurt, Elliott is soon drawn into a dark and disturbing world of chilling desires. And as the doctor edges closer to the terrible truth, he finds himself lost in a provocative and deadly maze of obsession, deviance and deceit where the most harmless erotic fantasies... can become the most deadly sexual nightmares!
