In Los Angeles, the gambler Paul Weston is a loser, and owes a lot of money to the dangerous mobster Freddie. When he is brutally beaten and the life of his former wife is threatened by the Freddie, his acquaintance bartender Vinnie sends him to Dr. Charlie Brooks first and then he convinces him to participate of a heist in the jewelry district with the professional thief Gene to raise the necessary money to pay his debt. Meanwhile, the stock market broker Roger Hargitay finds that the company where he works embezzled US$ 5,000,000.00 from their clients and he will be arrested in a couple of days. His boss Ed Koster convinces Roger and two co-workers to participate in an easy robbery of a jewelry planned by an inside man. On Saturday morning, both gangs arrive in the same jewelry for the same heist at the same time.
