Based on the best-selling book by Ben Masters, Unbranded is the story of four friends who set out on an unprecedented 3,000-mile horseback journey through the most pristine back-country of the American West; from Mexico to Canada they rode mustangs across an almost continuous stretch of public lands, border to border. Ben Masters, Jonny Fitzsimons, Thomas Glover and Ben Thamer are recent graduates and they decide to delay their entry into the responsibilities of adulthood and instead embark on a grand adventure. The ride takes over five months through the harsh, rugged, but strikingly beautiful terrain of Arizona, Utah, Idaho, Wyoming and Montana and tests the men's strength, courage, endurance, and friendship.
