The story of Henry McBride, a down and out cowboy with a painful past he can't drink away. Living on his last dollar with nowhere to go, he ends up working the last place an old cowboy wants to be: A dude ranch. It is here he meets the owner, Jessie King, a no-nonsense rancher with a deep love for horses. McBride's self-discovery begins when she introduces him to a new way of training a troubled mustang, a horse whose past and temperament mirror his own.
