Deep in the heart of the canyon, Little Pinto is just three weeks old. Still a bit unsteady on his feet, he must be ready to travel with his family, a band of rare wild mustangs, as they search for water along the desert flats.

At his signal, they are ready to scatter to safety, whether a strange stallion threatens or a whining plane swoops overhead. But can Little Pinto keep up?
