J. Ward Thomas of Park Avenue leads a double life as an investment broker and as notorious gambler Spade Martin, despite the protests of his beautiful wife Natalie, a nightclub singer who retired when they married. Spade's younger brother "Chick" wires Spade from Seattle that he has quit gambling for a job in real estate and is about to marry a nice girl named Betty. Relieved to find his kid brother is straight, Spade sends him $10,000 cash as a wedding present. When a woman posing as a pregnant wife comes to Spade for a loan, Spade gives it to her. Later, when Steve Burdick, the woman's supposed husband, brags in a bar that he made a fool of Spade, Spade's hit man, Trigger, kills Burdick. Tired of Spade's gambling, Natalie books a return engagement at Cafe Nocturne, telling him that she is a singer rather than a wife now.
