It's a story about two cowboys. They are friends and one of them is very good with horses. The other one (or the guy who's good with horses) has rights, or should had rights over a farm that belongs to his family.
All I remember is that they both decide, for some reason, to ride to Mexico. I know that one of them get arrested and suffer a lot while in prison. The other one gets a job in a farm, working for a rich Mexican guy who hires him to take care of the horses and other animals. This guy falls in love with the boss daughter.
