A pair of psychotic hoodlums and an equally demented nymphomaniac woman terrorize two young girls on a train trip from Germany to Italy.

Renowned gunman Richard Martin is traveling on a train, held up by Billy Kane, a former student of Martin’s. Kane spares Martin, but only after shooting his hands. Years later, Martin meets an escaped convict, wrongly convicted for the train robbery. Martin trains his new student and both men seek out Billy Kane.
