Vengeance Valley

Directed by Richard Thorpe

With Burt Lancaster, Robert Walker, Joanne Dru, Sally Forrest and John Ireland

A cattle baron takes in an orphaned boy and raises him, causing his own son to resent the boy. As they get older the resentment festers into hatred, and eventually the real son frames his stepbrother for fathering an illegitimate child that is actually his, seeing it as an opportunity to get his half-brother out of the way so he can have his father's empire all to himself.
