Marie (Simone Signoret), a woman of considerable beauty, is distressed at her treatment by Roland, a criminal who is a part of a local syndicate. When Marie is introduced to the handsome stranger Georges, a humble carpenter, she instantly falls in love with him, much to the chagrin of Roland. When Roland's jealousy builds after a number of meetings between Marie and Georges, Roland decides to confront Georges behind a club where several members of his syndicate watch. After Georges gains control of a knife that had been thrown between them to initiate the fight, Georges manages to stab Roland in the back after a brief scuffle, killing him almost instantly. When the police arrive at the scene, everyone flees, including Marie, who seeks refuge away from the syndicate at a nearby village.
