In a technologically primitive twenty-first-century America, Matt Simpson, Mimla Caceras, and David Hasgard battle the evil, ambitious Arthur Gladstone and rivals from the territory of Dorado.

Their discovery of the vaccination serum to stop the Death Enzyme, an AIDS-like virus, threatens to divide the members of TRIO as Matt and Mimla disagree over the strategy for the serum's use, and David becomes caught in the middle.

Matt, Mimla, and David match wits with two ruthless foes—Arthur Gladstone, the evil dictator of Dorado, and Archaeus, a reincarnated god—as they struggle to protect a powerful new source of energy, gallium, from Turtalia's enemies.
