Dismissed from the church because of his seemingly undue intimacy with the schoolteacher, the young minister becomes an evangelist and, after an incident in which he thrashes the drunken sheriff, is appointed sheriff by the mayor. In the girl's home he sees a picture of her father, whom he recognizes as identical with that on a circular calling for the arrest of Idaho Mac, a notorious desperado. He promises the girl that he will never use his gun against her father, but sends his deputy, the ex-sheriff, to apprehend Idaho Mac at the border. The bandit, badly wounded by the deputy's bullets, reaches his daughter's house, and she thinks the sheriff false to his word.
