It is only with some reluctance that big-time hood Alphonse (Lino Ventura) allows himself to be persuaded that a major painting-theft planned by some formerly small-time gangsters is a good idea. He gives the idea his backing and support and winds up holding the bag for the crime as the others escape. On emerging from prison, he wreaks havoc on his betrayers, until a pretty girl stops him in his tracks. ~ Clarke Fountain, Rovi
