1880 Texas.  A man and his 15 year old son are in town to get a few things.  The man sees a guy being beaten terribly by 3 men.  A young boy of about 10 is watching the beating, but does nothing.  The man decides to help even the odds, but he's beaten to death by those men.  The son tries to help, but he's too young and weak to stop them.

 

 

Ten years later, the son, now 25, rides into town on a mission.  A mission of revenge against those four who killed his pa or did nothing about it.  Hugh Lambert will have his revenge...or die trying.
