This is a lovely documentary about a cowboy named "Buck," who holds training clinics for horses and people with horses. He "breaks" colts in a NICE, RESPECTFUL way, rather than being violent or using fear to get them to obey. He is so connected with the horses. The documentary is largely about Buck and his life, but there are also some heartbreaking horse stories. I might have cried.
I highly recommend this movie. Though I am vegan and have some opinions about "using" horses, Buck's story is an interesting and heartfelt one, and the film is just really well-made.
