It is 1865 and former Brigadier General Frank McGrew has not forgotten the loss of his brother at Fort Pillow and the everlasting thorn in his side, ex-Confederate John Lee Johnson. Unfortunately while recklessly acting on his hatred for Johnson and exacting revenge for his brother's death, McGrew has lost his rank and prestige in the military. Still, he remains determined to bag the big Texan, no matter what it takes or costs him personally.

McGrew ultimately hires a group of disciplined gunmen and its infamous leader, Sabbath Sam, to help him carry out his mission. Sam, known as the fastest gun east of the Mississippi, has his own reasons for hunting Johnson. As Sam pursues Johnson with a rabid hatred, he and his pack of twenty-one hired killers ride toward Texas. While McGrew anxiously awaits the news whether Johnson is finally eliminated or if he has managed to escape death once again, two of the most deadly gunmen in the West finally meet in a showdown deep in the Nations where fate is left to determine the outcome.

In this western thriller, an ex-military general continues his vengeful mission to eliminate his greatest enemy, with help from a notorious gunman and his gang.
