Wealthy Easterner Dick Latham, determined to disprove his father Amos' accusation that he is an idler, rides the rails West to the mining town of Twin Bridges. Hugh Godson, the town's corrupt political boss, appoints Dick sheriff, supposing him an easily manipulated tenderfoot. To Godson's dismay, Dick proceeds to clean up Twin Bridges, closing the saloons and gambling dens, and forcing even the most hardened miners to attend church.
