Mary Regan, the child of an heiress who married a handsome thief hoping to reform him, then died when he went to prison, refuses to marry New York District Attorney Robert Clifford because she fears that the family's past will hurt his career. After refusing to cooperate with her father's gang members, Jim Bradley and Peter Loveman, Mary goes to the mountains. Bradley and Loveman get Jack Morton, a dissolute youth from a wealthy family, involved with Nina Cordova, an adventuress. After winning the trust of Morton's father, Loveman takes Morton to the mountains, supposedly to get him away from Nina, but really to involve him with Mary. Morton falls in love with Mary, and she marries him hoping to effect his reform. After Morton tries to hide the marriage from his father, the gang tries to blackmail Morton, Sr., but Mary contacts Robert, and after Morton is killed in a fight, the gang is arrested. Robert then convinces Mary to be true to her heart and marry him.—AFI
