On the Mexican border, Jim Jason forms a partnership with Don Felipe Arrello although he is troubled by a clause in their contract which states that if one of the partners dies, the other will inherit their ranch. When the ranch begins to prove profitable, Felipe hires an assassin to kill Jim, but the cowboy discovers the plan and gives the killer a sound beating. Jim's sweetheart, Ruth Allen, who has come to the area with her father to restore the old Spanish architecture, sees the fight and assumes that he is mistreating his men, but his concern for little Carmelita, who is suffering from typhoid fever, convinces Ruth of Jim's kindness. Felipe tries once again to kill Jim, who leads his cowboys in pursuit of the villain, but upon reaching Felipe's hideout, they learn that Dolores, his betrayed lover, has already killed him.
