Marko (Hugo Haas), is searching for a lost gold mine with his young partner Ray Brighton (John Agar). They find the mine but Marko doesn't want to share the profits and devises a complicated scheme to get rid of Brighton. So, Marko weds buxom and blonde young Peggy (Cleo Moore) figuring that, after the three spend the winter together in a shack far from civilization, he will sooner or later catch them in adultery, and can use the "unwritten law" to kill Brighton and thus escape punishment from the law. But things seldom turn out as planned.
