 Al Walker, a notorious gunfighter, has come to North Fork to die. He has an incurable illness and, since he had once been a wealthy and prominent lawyer, believes he owes it to his family to have his death certificate read "natural causes" instead of "killed in gunfight". However, the Porter brothers--a gang of vicious killers and bank robbers--have followed him to town and plan to take their revenge on Walker for killing their brother, and they ll stop at nothing and no one in order to do it.
