Tom Devon, known to his society friends as Reginald Briand, is the mastermind behind an organization of gentlemen thieves, which includes Jimmy Stevens and Rudolph Gambier. Jimmy falls in love with Tom's innocent daughter, Gloria, after he rescues her from an embarrassing scene in a restaurant. Tom disapproves of the romance and decides to dissolve the partnership. He pays Rudolph his share of the profits, then tries to dissuade Jimmy from seeing Gloria. Rudolph believes he has been cheated and kills Tom. Jimmy is convicted of the murder, but Gloria is determined to find the real killer. When Rudolph returns for the remainder of the spoils, Gloria poses as a thief and wins his affections, then tricks him into confessing to the crime. Rudolph is mortally wounded by the police, and Jimmy is pardoned by the governor.
