Joseph Cotten plays a assistant bank manager who steals $500,000 from the safe late on a Friday. He plans to fly to Brazil with his wife (Teresa Wright) and child. They get as far as New Orleans; the wife finds out about the robbery and walks out on Cotten. Stricken by guilt, Cotten must now return to his home town and replace the money before he's found out on Monday morning. Writer/director Andrew L. Stone smooths out the unrealistic elements of The Steel Trap by filming extensively at real locations.
