While taking a shower, Kate Miller (Angie Dickinson), a middle-aged, sexually frustrated New York housewife, has a rape fantasy while her husband stands at the sink shaving. Later that day, after complaining to her psychiatrist Dr. Robert Elliott (Michael Caine) about her husband's pathetic performance in bed, she meets a strange man at a museum (Ken Baker) and returns to his apartment where they continue an adulterous encounter that began in the taxicab. Before she leaves his apartment, she finds papers which certify that the man has a venereal disease. Panicked, Kate rushes into the elevator, but has to return to his apartment when she realizes she's forgotten her wedding ring. When the elevator doors open, she's brutally slashed to death by a tall blonde woman wearing dark glasses. Liz Blake (Nancy Allen), a high-priced call girl, is the only witness to the murder and she becomes the prime suspect and the murderess's next target. Liz is rescued from being killed by Kate's son Peter (Keith Gordon), who enlists the help of Liz to catch his mother's killer as Detective Marino (Dennis Franz) who's in charge of the case is uncooperative in the investigation.
