Tracking outlaws Dobie Miller and Waldo Schmitt into a deadly desert, the notorious bounty hunter Iron Eyes is closing the distance between them with every beat of his determined heart. Yet the magnificent palomino stallion beneath his ornate saddle is starting to suffer. For years the deadly Iron Eyes has never been concerned about his horses, but since acquiring the powerful stallion, his attitude has changed. Iron Eyes knows that the horse has saved his life many times, due to its remarkable strength, but now it needs water badly. Every instinct tells the bounty hunter to stop his relentless hunt for the wanted outlaws, but then his steely eyes spot something out in the sickening heat-haze: It is a towering fortress. Iron Eyes presses on.
