Molly Helmer (Norma Shearer) is released from reform school. One night at a dance hall, an inventor named David Page (Malcolm McGregor) rescues her from a stranger's unwanted advances. Molly falls in love with David, but David is oblivious to her feelings. He invents a safecracking device, and Molly encourages him to sell it to Judge Banning (Fred Esmelton). David meets Banning's daughter, Florence (also Shearer), and they fall in love. Molly steps aside, believing they belong together.
