Widely regarded as one of Fritz Lang’s best films, Scarlet Street is based on the French novel La Chienne (The Bitch) by Georges de La Fouchardière. Somewhere between film noir and black comedy, the plot revolves around a man in mid-life crisis who befriends a young woman whose fiancé persuades her to con him out of some of the fortune she thinks he has.
