 Dissension arises between cattlemen in Osage County, Texas, and sheepherders who have settled there and use the same watering stream. Mart Dalton (Charles Morton), son of a wealthy cattleman, quarrels with and kills one of the settlers, thus placing Sheriff Larry Williams (Buck Jones) in a delicate position; for he is Mart s best friend and is engaged to Mart s sister June (Miriam Seeger). However, sworn to do his duty, he arrests Mart, incensing the cattlemen, who help Mart escape, leaving Larry wounded.
