By 1884, Mission, Arizona was a dying town. It had once shown promise as a commercial center between Mexico and the territory, but when the railroad connected Los Angeles to Deming, New Mexico, its fortunes began to wane. A tragic event forced Mission's sheriff of eight years, Jed Dunston, to turn in his badge and leave behind the woman he loves. Weeks later, a timely message from Mission informed him of an unspeakable evil that gripped the town and imperiled everyone he'd once protected. Almost sixty years old and lacking confidence in his abilities as a lawman, Jed fights against the inner fears that haunt him. However, the former lawman doesn't hesitate in his decision. He rides back to Mission with a ragtag posse to face a pitiless, bloodthirsty outlaw and his band of cutthroats. If anyone in Mission is to survive, he'll have to face...Hell's Gunman.
