During his travels in the desert, Max uncovers an old and rusty gun. When he comes upon Jonas Cord, Sr, a traveling gunsmith, he tries to rob him. Cord,  recognizing that Max's revolver is not loaded and is useless, convinces Max that his plan has failed. Max tells Cord of his vengeful journey. Cord takes pity on him, takes him in, feeds him and teaches him how to shoot. Max hunts the killers, who have separated. He tracks down Jesse Coe to Abilene, Texas. With the help of dancehall girl Neesa, a woman from the same tribe as his mother, he confronts him in a salon. Coe escapes and a knife fight ensues in a nearby corral. Coe is killed but Max is severely wounded. Neesa takes him to her tribe's camp, where she nurses him back to health. They become lovers. Once he recovers, Max leaves Neesa to continue his pursuit.
