Emily Cottrell, one of the most respected members of a large gang of crooks headed by Fraser Grimstead, is caught while robbing the home of wealthy David Parrish. Emily accepts David's offer of a home and a chance to go straight, but Grimstead is unwilling to lose her, and he insists that she help him steal the famous diamond collar, The Tower of Jewels, which is in David's possession. When Emily refuses, Grimstead threatens to expose her past to Wayne Parrish, her benefactor's son with whom she is in love. Grimstead and the gang surround the Parrish home, then Wayne's cousin removes the jewel case to throw suspicion on her rival for Wayne's affections. Emily's innocence is established later, and her reputation is further cleared by Grimstead, who is shot by the police. With his dying breath, Grimstead describes Emily's gentle birth and states that she is fit to marry Wayne.
