A clean cut narrative of endurance and perseverance also lightly examines the problem of guilt as Andy Smith, a boy of mysterious origins, comes to Justin Allan, now old and forced to make his way alone in the Colorado mountains, at the very moment when he is faced with the task of shooting a badly injured wild mare. Neither Justin nor Andy wants to kill the mare. Against all logic, they finally get her up off the ground and into the stable where in a few days she foals and then, mostly under Andy's care, miraculously begins to recover. As the mare goes, so does Andy, until the time when she and Andy as a quarter-horse and rider team enter a rodeo and encounter their rival in Andy's crooked stepbrother whom he thought he had killed in a fight. This lacks the psychological probing to give it real depth but it is convincing in its honesty and simplicity.
