Barbara Stanwyck as "Gambling Lady" successfully plays her way through an unusually complex plot. Her father, Mike, the "last of the honest gamblers," commits suicide, in preference to turning dishonest, when he goes broke. Lady Lee gets a job with a crooked gambling syndicate and despite all temptations, she always plays on the square. While playing poker for the syndicate, on Park Avenue, Lady meets wealthy young Garry Madison (Joel McCrea), who falls for her and pursues her everywhere, even after she goes to jail for the crooked dealings of her syndicate. Finally she marries him, only to find he has been mixed up in an affair with Shella Aiken (Claire Dodd). Meanwhile Lady Lee again becomes entangled with her former employer in the syndicate. Mutual jealousy arises; and after an incidental trial for murder and a highly dramatic card game between Lady and Shella, Lady divorces Madison because it is the only way she can save him from a false murder charge, and at the same time play the game square with all concerned. After the divorce, they both find out what really went on; they make up, and leave on a honeymoon to Norway. Through all the intricacies of the plot, Barbara Stanwyck seems to emerge victorious. And it is her personality dominating the entire show, which renders the picture worth while.
