The Peña gang ravage the south-west, plundering and killing with impunity. Until, that is, they kill Ben Morrison's brother for a fortune in rubies. Ben considers himself a used-up former lawman, but desperate for revenge, calls on ex-manhunter, Duel Winston, for help.

Duel, though, has settled into a peaceful life of ranching, and is reluctant to risk his new-found happiness. Until, that is, the ghosts of the past come a-haunting, and he takes to the trail again.

Trapped in a hellish ghost town with a band of ruthless hardcases, Duel finds himself locked in a bitter struggle just to stay alive. And the showdown on the horizon promises to send him into retirement - permanently!
