When straight-laced Jefferson finds out his drug-dealing brother is dead, he returns to São Paulo with his childhood friend to identify the body. The journey raises memories of their shared childhood and poses a choice for their future.

Chino Valdez is a loner horse breeder living in the old west. Partly a loner by choice, and partly because, being a 'half-breed', he finds himself unwelcome almost everywhere he goes. One day, a young runaway named Jimmy shows up at his door looking for work and a roof over his head. Reluctantly, Chino agrees to take him in and teach him the art of raising, breaking and breeding horses, until the pair finally begin to accept each other.
