Jim Houston, the "Shootin' Iron" Parson, comes to Barren Gulch to reform the morals of the frontier community. He receives the support of "Birdshot" Bivens, the sheriff of the county. Jim's wife, Mary, however, is a weak character. She falls a prey to the seduction of Dr. Hardy, the village gambler and saloon keeper, and elopes with him. Jim Houston, forsaking the ministry, goes to the mountains and cares for his child in a log cabin home. Later the child falls very ill. Mary, in a mountain storm, comes unwittingly to their door. Dr. Hardy is sent for as the only physician in the district. He ministers to the child and confronts Houston, who intends to kill him. Mary is asked to make her choice between Houston and Dr. Hardy. She points towards the child and goes to its bedside. Houston forgives his wife and instead of killing Hardy permits him to go unharmed.
