Cutthroat Comancheros, wandering banditos, the Mexican Army, the Fourth Cavalry — and Miss Vanessa Fontaine — all want Duane Braddock, who has the fastest gun in the West and much more than a price on his head. But it is the Apaches who leave him for dead in the Coahuilian Desert. Found by a ragtag outlaw band led by an ex-Confederate soldier, Braddock is brought back to the land of the living. By the time he is well enough to run, a greedy plan to seize half-a-million dollars of Army payroll is in place. The dynamite is set, the fuse is lit, and the Pecos Kid has to pick: kill or die.
