When Marshal Brent McAllister is told by the doctor that he has less than a year to live, he decides that he will not wait passively for death to overtake him. Instead, he determines to hunt down and dispose of the worst men in the state; vicious and depraved criminals, whom the law cannot touch. It is McAllister's expectation that in the course of this quest, he may find a quick and easy death from a bullet, rather than a lingering end in a hospital bed.
