After the Nazis lock up an Italian general who was about to become a turncoat and hand his army over to the Allies, five convicts are given a chance at redemption in exchange for infiltrating enemy territory and rescuing the general. Raf Vallone, Mickey Rooney, Edd Byrnes, Henry Silva and William Campbell play the commandos -- led by British intelligence officer Stewart Granger -- in this tense World War II drama directed by Roger Corman.
