Mustang is the sweeping story of the wild horse in the culture, history, and popular imagination of the American West. It follows the wild horse across time, from its evolutionary origins on this continent to its return with the conquistadors, its bloody battles on the old frontier, its iconic status in Buffalo Bill shows and early westerns, and its plight today as it makes its last stand on the vanishing range. With the Bureau of Land Management proposing to euthanize thousands of horses and ever-encroaching development threatening the land, the mustang’s position has never been more perilous. But as Stillman reveals, the horses are still running wild despite all the obstacles, with spirit unbroken. Hailed by critics nationwide, Mustang is "a stunner and a heartbreaker" (Tom Ashbrook, NPR's On Point).
