This portrait of wild mustangs and the men and women who train them focuses on the annual Extreme Mustang Makeover Challenge in Fort Worth, TX in which 100 trainers (both professionals and amateurs) set out to train a totally wild mustang in just 100 days. The trainers then show their horses in competition before putting the animals up for public auction. Here, a half dozen trainers and their mustangs are featured in various locations, from the Navajo nation to the Texas range to the rolling hills of New Hampshire. We follow them from the first uneasy meeting between the trainers and their horses, up through the Ft. Worth competition. What starts out as a cautious and suspicious relationship evolves into a powerful bond.
