Just out of prison, ex-con Ugo Piazza meets his former employer, a psychopathic gangster Rocco who enjoys sick violence and torture. Both the gangsters and the police believe Ugo has hidden $300,000 that should have gone to an American drug syndicate boss.

The movie is set during World War II in the days just prior to the D-Day invasion. A special parachute unit is sent to destroy a German flame thrower installation on Omaha Beach.
