Hitchcock thriller. Spinsterish Lina McLaidlaw (Joan Fontaine) lives in an English manor house with her wealthy parents, and never has any suitors. That is, until the charming Johnny Aysgarth (Cary Grant) sweeps her off her feet and proposes to her. The couple are soon married, despite opposition from Lina's father, but Lina becomes suspicious when Johnny lies to her over losing his job. When Johnny's friend Beaky (Nigel Bruce) dies mysteriously after losing interest in a real estate deal they were planning together, Lina suspects Johnny of murder, and comes to believe that she will be his next victim.
