The narrative follows Henry McBride, a cowboy struggling with a haunting past that he can’t escape through alcohol. With his finances depleted and no destination in sight, he reluctantly takes a job at a dude ranch, a place far from ideal for a seasoned cowboy. There, he encounters Jessie King, the pragmatic owner who has a profound passion for horses. McBride embarks on a journey of self-discovery when Jessie shows him an innovative method to train a difficult mustang, a horse whose history and disposition reflect his own.
