Taggart

Kent Taggart's family, with their cattle stampeded, are killed by those who started it. In a fair gunfight, he kills the man's son responsible for it all and when he runs, a warrant is issued and a price put on his head.
Taggart's family is slaughtered by a rival rancher. Taggart mortally wounds the rancher and kills his son. Before he dies the rancher hires three bounty hunters to avenge him with the promise of $5000 as a reward. Taggart must flee into Apache territory to escape the wrath of the trio of hired killers.
