FBI Special Agent Demzey knows nothing about archaeology; his specialty— anomalous crimes, the fringe edge of the aberrant and the unknown. Demzey is investigating a recent rash of vicious and brutal murders, the clues surrounding the killings both disturbing and inexplicable. He and his assistant Connie Wegman catch a break when they discover remains of two monstrous creatures unknown to science, believed to be a race of aliens responsible for attacks on humans across the globe.

With the death toll ticking ever higher, scientists and intelligence agencies on every continent search for the source of these vicious creatures, until the combined efforts of Duccati and Demzey begin to unravel the mystery, though what they uncover could spell the end for the human race.
