Charles Bronson gives one of his best performances in this little-known European western. He looks very relaxed and comfortable as Chino, a half-breed cowboy who takes in a young runaway (Vincent Van Patten) on his small ranch, even smiling and laughing out loud several times. Chino's character is more complex than the typical western loner; he's not always sympathetic and handles the local racists in an atypical way for both the genre and for Bronson. The screenplay itself is quite loose, even taking occasional breaks from the main story to show local colour or attempt humour.

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.
