This is the story of Leon Miller, a bounty hunter in a post-apocalyptic world characterized by retrogressing technology and a civilization teetering on the brink of chaos. As a result of the decimation of Earth's environment, human mutants have evolved, some with preternatural characteristics and extraordinary abilities. They are seen as a threat and have been outlawed by the fragile and corrupt world government. Many have been marked with a spider web of blue dye beneath the skin of their heads and bounties have been placed on those who have become fugitives. Miller makes his living tracking them down.
