A "bowed and bandy-legged old cowboy," Print Ritter is a man with miles of dusty trail under his well-worn belt. When his sister dies and leaves all she owns to him, Print feels it's only right to take her estranged son under his wing. The two horsemen - one old, one young - set off to seek their fortune on a last, long drive across the West. But the simple rhythm and reverie of trail life doesn't last, and before long they find themselves risking everything to save five kidnapped Chinese girls from a life of prostitution. Thus begins an epic and perilous journey that changes forever the fates of these young women, their unlikely guardians, and the other characters they meet along the way.
