Marshall Cowan and the mercenary Miller are both separately hunting the outlaw Catlow. During the Civil War both Cowan and the always smiling Catlow were comrades. Catlow helps Cowan, when he is wounded in the right leg by an arrow from the Apaches, despite Cowan hunting him. Catlow escapes with help of his gang. Catlow then robs a Mexican gold shipment, worth $ 2,000,000. Catlow flees with the stolen gold through the dangerous territory of the Apaches who, besides Miller, Cowan and the Mexican cavalry, are hunting for him and his gang of outlaws.
