Charlie Chase, Katherine Grant and Bull Montana aspire to be society crooks. As their first job they decide to nab the Kadir brooch which they read has been given from Mrs. Van Courtland to her daughter. The three start out for the Van Courtland home and collide with an auto carrying the Metropolitan Trio, who are to entertain at a party at the Van Courtland home. The crooks persuade them the party has been called off and proceed to the party, announcing themselves as the performers. They do steal the brooch, but reform before the final fade out.
