Giff Hoyt, a cafe owner in Cabo Blanco, Peru after World War II is caught between refuge-seeking Nazis and their enemies. After the murder of a sea explorer is passed off as accidental death by the corrupt local police, Giff becomes suspicious. The police chief also intimidates a new arrival Marie, and Giff intervenes to help her. Giff suspects Beckdorff, a Nazi refugee living in the area. Beckdorff, it emerges, is seeking to uncover sunken treasure.
