The debauched son of a wealthy family, Dick Gilbert, is forced to raise money to pay off gambling debts and uses a valuable family jewel as security for a loan from Prince Borkoff, but it is stolen by Morris, a gambler. To save face for Dick, his sister Judith determines to recover the gem, and in the guise of Canada Nell, a girl of the streets, she meets Morris, who becomes infatuated with her. She learns that Mrs. Smith, a social climber, has purchased the jewel and (finding that it is stolen) plans to use it to further her position. Judith impersonates herself at a party and retrieves the jewel; through a series of maneuvers she evades capture by De Mornoff, a jewel thief, and returns the jewel to the family safe just before her brother pays off his debt. Bruce Gordon, a reporter, who wishes to reform her, arrives with the police on the tail of the gang; Judith reveals her true identity and accepts the proposal of Gordon.—Pamela Short
