Buck Brannaman, a gentle spirit and sage on horseback, travels the country for nine gruelling months a year, helping horses with people problems. BUCK follows Brannaman from his abusive childhood to his phenomenally successful approach to horses: a real-life "horse-whisperer", he possesses near magical abilities as he dramatically transforms horses - and people - with his understanding, compassion and respect. A truly inspiring story of how an ordinary man has made an extraordinary life for himself, in spite of tremendous odds.
