Roy Scheider plays a newly divorced New York psychiatrist named Sam Rice, who discovers that George Bynum (Josef Sommer), one of his prominent patients, has been murdered. Bynum was the curator of antiquities for Crispin’s, a high-scale auction house, who engaged in a sexual affair with Brooke Reynolds (Meryl Streep), a younger woman who worked with him. During his counseling sessions, Bynum told Sam all about Brooke in such vivid detail that Sam thinks he might have fallen for Bynum’s mistress himself. Those feelings get reinforced when Brooke visits Sam’s office to hand him Bynum’s wristwatch he left in her apartment the night of his death. Sam becomes infatuated with Brooke, but as he pursues her romantically, he’s also frightened of her because she might be Bynum’s murderer. As the police press him for evidence, Sam begins following Brooke to learn more, only to feel she might already be stalking him as her potential next kill. Robert Benton writes and directs.
