In the 22nd century, Earth has been harvested by a race of aliens known as the Xini. In the aftermath, all the planet's resources have been stripped. Dakota sets out from Dallas in search of his lover, Grayson, who vanished on his way to St. Louis after the invading fleet departed.
Dakota faces unknown dangers in the devastated plains of northern Texas and southern Oklahoma as scavengers -- human beings reduced to shells after the Harvesting -- roam the earth attacking anything that moves in an effort to survive.
He finds a group of survivors struggling in what little remains of Oklahoma City, led by the tough, handsome Colonel Welch. While Mother Nature unleashes a fury of natural disasters to purge herself of the Xini rape, Dakota must decide whether to stay with the colonel and help him make the colony viable, or continue onto St. Louis to find Grayson.
