Forty years ago the American West Coast village of Longford was subjected to a secret military test-a biological agent that drove the inhabitants insane. Gassed, isolated, and declared off-limits, Longford disappeared when the valley was flooded. Now drought has caused the village to emerge, and not everything there has remained dead. A small group investigates, including ex-Marine Robert "Bone" Bonham and Vince (from Relics). More than scientific secrets are hidden in Longford-mythological creatures are stirring, including the last of the Nephilim, who seeks to recruit the creatures in a war against Mankind.
