Removed from an orphanage, Nance Olden is taken to live at Mother Hogan's boarding-house for crooks. There she becomes Tom Morgan's partner, helping him steal a jewel from Edward Ramsey at Union Station. She makes her getaway by slipping into a nearby carriage; when the owner, Bishop Van Wagenen, enters, she pretends to have lost her mind and is taken to Mrs. Ramsey's, where she keeps up her deception. Tom trails her there, where he is arrested. William Lattimer, Nellie Ramsey's fiancé, is not fooled by Nancy's deceit and persuades her to reform and utilize the talent for sketching which she has displayed. Nellie, however, jealous of William's interest in Nance, plants evidence making it look as though Nance stole a purse, but Tom, just escaped from jail, sees and reports Nellie's trick. Finally, Tom is sent back to jail, and William and Nance are reunited.—Pamela Short
