District Attorney Graham starts a crusade against the city's gambling houses. Judson Flagg, a lawyer, owns a notorious joint and knows that nothing can stop Graham once he gets his hand in. He then enters the fight armed with every weapon an unscrupulous man can employ. Through Mrs. Cuyler Hastings, a society woman who owes him a gambling debt, Flagg introduces Joe Hunter, his aide, to Aline Graham, daughter of the District Attorney. Hunter, polished, dashing and handsome, is seemingly devoted to Aline, and manages to marry her secretly. Later, in a raid on Flagg's place, Hunter shoots Graham and runs to Aline with the plea that unless she gives him money he will divulge the whole affair, saying that the marriage was a fake to aid some political enemies of her father. He leaves with her necklace, but she writes to him at Flagg's office begging him not to desert her. The gambler gets the letter and arranges an interview before a cunningly concealed camera, with the hope of getting her in a compromising position. How she is finally rescued and her fair name saved makes a charming ending to this drama.
