Young drifter Gino (Massimo Girotti) stops at a diner/gas station, where he is immediately attracted to Giovana (Clara Calamai), the young wife of the owner, Giussepe (Juan de Landa). Frustrated by the struggle of working at the dreary diner with the unappealing Giuseppe, Giovana seduces Gino, then convinces him to help her murder her husband. Eager to remain with Giovana but wary about replacing Giuseppe, Gino agrees, and the couple engages in a crime that leads to more betrayal and death.
