A film about two brothers, one sickly that their uncle kills their father over some coins he had stached away. The older brother takes the coins and the two are on the run. The elder brother takes up with a girl who wants to steal the coins. The uncle catches up to the boys and tries to kill them. I believe the girl shoots and wounds him and the boys are taken in by a family member?
