"Your horse is a mirror to your soul, and sometimes you may not like what you see. Sometimes, you will." So says Buck Brannaman, a true American cowboy and sage on horseback who travels the country for nine grueling months a year helping horses with people problems.

Buck, a richly textured and visually stunning film, follows Brannaman from his abusive childhood to his phenomenally successful approach to horses. A real-life "horse-whisperer", he eschews the violence of his upbringing and teaches people to communicate with their horses through leadership and sensitivity, not punishment. Buck possesses near magical abilities as he dramatically transforms horses - and people - with his understanding, compassion and respect. In this film, the animal-human relationship becomes a metaphor for facing the daily challenges of life. A truly American story about an unsung hero, Buck is about an ordinary man who has made an extraordinary life despite tremendous odds.
