Classic 1940s American film noir which tells a grim, complex tale of love and betrayal. Private detective Jeff Bailey falls for Kathie Moffett, the mistress of mobster Whit Sterling, when the mobster hires him to track her down in Mexico after she shot Sterling and stole 40,000 pounds from him. When she double-crosses Bailey and returns to the gangster, the detective changes his identity and drops out of sight as a garage owner. Sterling still wants his money back, however, and he and the duplicitous Kathie plot to lure the Bailey into a vengeful scenario.
