Mack Bolan, wounded and run to earth, is trapped in an isolated Kansas farmhouse. Outside, the dogs of death are waiting for nightfall before they rip him apart. As a hired killer, "The Cowboy" sells his service only to the highest bidder. Although he has his mark cornered, he knows this hit is the toughest yet. By morning hell deliver the targets head to his demonic employer. The Executioner rediscovers, in the indomitable spirit of a struggling farm family, the eternal dream of the American heartland - his land, his dream. These are the people he always fought to protect - the good and the innocent. But his very presence makes them certain victims - unless he destroys the slavering menace.
