Shelly is a miniature horse that lives on a well-known horse ranch that trains horses for all sorts of duties, from horse racing to plowing farms. Shelly looks up to all the other horses on the ranch. She wishes that she could do what the other horses do but knows she will never be able to do so because of her size. Shelly is left by herself in a small corral away from the other horses until one day, when a special group of people come to visit the ranch. Their interaction with Shelly changes their experience on the ranch. It's that experience that, in turn, gives the rancher a different view of what value Shelly can bring to the ranch and helps Shelly find her purpose.
