Buck is a documentary about legendary horse trainer Dan "Buck" Brannaman, the modern day horse whisperer and inspiration for both the book and film alike. His horsemanship skills are legendary because he can train a horse to do just about anything in nearly ten minutes without touching the horse.
His natural abilities and skills on are display and he tours the country giving seminars on how train troubled horses. He helps cowboys with their colts and he helps professional equestrian riders perfect their dressage. You have to see it to believe it. The only disappointing part is that there is one horse in the film that could not be helped and the owner decided to euthanize it.
