A rich woman [Barbara Stanwyck] and a calculating insurance agent [Fred MacMurray] plot to kill her unsuspecting husband after he signs a double indemnity policy. Against a backdrop of distinctly Californian settings, the partners in crime plan the perfect murder to collect the insurance, which pays double if the death is accidental. Directed by Billy Wilder from a screenplay he wrote with Raymond Chandler, and from the novel by James M. Cain.
