Bank robber Jake Larribee, whilst looking for a suitable target, saves Blaze Morgan, a one-time amigo of William Bonney, from a cattleman's hanging. The youthful Blaze's handiness with his pistol lands them in deeper trouble. Now being beholden to a sutler and his daughter they take on Simpson, the biggest rancher in southern New Mexico, and his hard crew of the Slash Y ranch. Allied with three Mexican boys and their grandpappy, they, with both gun and knife, begin a guerrilla war against the Slash Y. It was all destined to end in one final bloodletting shoot-out.
