Faith Miller, a school teacher, inherits ten thousand dollars. Edson, McGill and Slade, three enterprising crooks, own the Moonflower, a worthless mine. Slade goes east to unload and hearing of Faith's good fortune, she falls an easy prey, buying a share in the mine for nine thousand dollars. Advised by friends to take a rest, Faith goes to inspect her mine. Arriving at the town, she is insultingly approached and the man who has annoyed her is knocked down by Jim Ralston, a young mining engineer. She goes to the home of Big Annie, who tells her that the mine is worthless. The miners, touched by her beauty and helplessness, engage her to teach their school, the only available pupils being Pete, a half-wit, and Jim, who is held in connection with a hold-up committed by Edson and McGill. At first Jim rebels, but when he sees the teacher, he becomes a willing student. Faith recognizes him as her protector.
