Wild Horses & Renegades examines the plight of America's wild horses and the rapidly deteriorating condition of our wild and beautiful public lands in the majestic, haunting American west. Through interviews with scientific experts, ranchers, historians, wild horse owners, animal rights activists, environmentalists, movie stars (Viggo Mortensen, Daryl Hannah, Sheryl Crow, Willie Nelson) uranium prospectors and many other colorful characters, the filmmaker examines the origins and effects of recent legislation clearing the way for the slaughter and removal of wild horses in America.
