Rynning and his rangers investigate a gang of clever cattle rustlers who steal only a few head at a time in order to better conceal their movements. They get a lead when a dying cowhand identifies one of the murderous crooks as the brother of a wealthy rancher. When Travis is forced to kill the accused man when he resists arrest tempers flare in town and Rynning orders his young protégé to head for the hills to find the herd of stolen stock and the rustlers who are behind the thefts.
