Luce rossa (1949)

Nick Cherney, in prison for embezzling from Torno Freight Co., sees a chance to get back at Johnny Torno through his young priest brother Jess. He pays fellow prisoner Rocky, who gets out a week before Nick, to murder Jess... who, dying, tells revenge-minded Johnny that he'd written a clue "in the Bible." Frustrated, Johnny obsessively searches for the missing Gideon Bible from Jess's hotel room.
