Baseball came west with the pioneers and settlers. Every town and even come ranches had a team. Young Tucker Beavers plays ball growing up on the Mountain Beavers Ranch. When he is fifteen his father gives him a herd of wild cows, which he fathers with the help of a mysterious cowhand and two brush-popping dogs. Later, Tucker helps avert an Apache outbreak by driving cattle to the Mescalero Reservation... only the beginning of the challenges he will face as a rancher in the wild untamed territory of the desert Southwest.
