In the eyes of legendary Arizona Ranger Sam Burrack, the line between right and wrong is clearly drawn - until he has to hunt down a criminal whose motives may outweigh the letter of the law...

Bank robber Willis Durant is a man consumed with hatred for the vicious pack of Border Dogs who murdered his family - and nothing and no one is going to get in the way of his revenge. Sam Burrack knows this - but the law is the law, and Durant has to stand before the court.

Then the filthy Dogs make the mistake of kidnapping the Ranger's partner, Maria. Now, a relentless lawman and a dogged outlaw must ally themselves to fight against an army of killers to deliver their own brand of vengeance.
