A robbery goes terribly wrong for a hapless criminal when he goes to knock off a jewelry store. Upon entering the store, the steel shutters immediately slam down and lock him inside until the police arrive. He is later sent to jail, but it doesn't take long before he befriends a big time crime boss inside. The two execute a successful break out and we soon find out that we don't really know the true background of these criminals or what is really motivating them. Franco Prosperi (Last House on the Beach)directs this revenge themed crime film with Ray Lovelock and Elke Sommer. With its clever plot twists, fist fights, motorcycle and car chases, this rare entry in poliziotteschi genre is an entertaining one.
