 It is 1957. J.C. Cullen is a young man from a small town, with a talent for winning at craps, who leaves for the big city to work as a professional gambler. While there, he breaks the bank at a private craps game at the Gem Club, owned by George Cole, and falls in love with two women, one of them Cole s wife. Infuriated, Cole wagers everything on the craps table, including the Gem Club itself, and he and Cullen have it out.
