Buck is an inspiring documentary about a man who was viciously beaten by his father in childhood and grew up bonding with horses.
At the horse clinics that he runs all over the country, Buck can take an unruly horse and sometimes within minutes render it docile and ready to saddle. Buck attributes all problems a horse may have to the people around it.
But there was one horse that although Buck could calm it for a short period of time, no one else could get close to it. It bit people in the face, attacked other horses and cars, crashed through fences.
One thing that Buck did that no one else could do was coax the horse into the horse trailer that took it to where it was put down.
