Bob Lemmons is famous for his ability to track wild horses. He rides his horse, Warrior, picks up the trail of mustangs, then runs with them day and night until they accept his presence. Bob and Warrior must then challenge the stallion for leadership of the wild herd. A victorious Bob leads the mustangs across the wide plains and for one last spectacular run before guiding them into the corral. Bob's job is done, but he dreams of galloping with Warrior forever to where the sky and land meet.
