When a ruthless bounty hunter tracks down a sadistic outlaw and guns down his entire gang in the desert, he tortures his prisoner in hopes of discovering the location of the money from his last holdup. Their horses are stolen in the night by renegade Chiricahua Apaches and the disparate pair are forced to make their way on foot across the desert to town, contending with the elements, the hostiles, and their own murderous distrust of each other.
