Beau Boone, starving, with half a left leg, at the end of his rope, falls off the train in the hell-on-wheels town of Nemesis. But Mr. Pettigrew intervenes. Beau owes him, but does he owe him his very life? Can a one-legged man sit shotgun in one of the toughest saloons on the Transcontinental? He can, if he doesn't have anything to lose.
