A forgotten evil waits in Vietnam's dark jungle...

It is 1969. Somewhere over South Vietnam, Captain Brandon Doran sits aboard an unmarked aircraft on final approach to a Top Secret military base. A shadowy government operative is offering him a deal. Brandon is listening. Intently. In exchange for wiping away Brandon's tarnished military record, all Brandon will have to do is ensure the recon team, to which he is about to be assigned, follows orders. Easy enough. Or so Brandon thinks.

Sergeant First Class John Nicholas has no time to be salty about the inexperienced officer sent to babysit him and his team; Recon Team Florida has gone missing near a remote village in the North. Now John, with Brandon and the mysterious "Smith" in tow, leads the elite Recon Team New York deep into North Vietnam on a rescue operation.

At first, John expects heavy resistance. But intercepted radio traffic suggests something near that village has spooked even hardened NVA. And soon after New York's midnight insertion behind enemy lines, John finds out what.

Confronted in the night by a merciless demon, John reacts the way any soldier would: He shoots it. But John discovers, far too late, pulling the trigger is the worst mistake he can make.

Flung headlong into atrocity and supernatural chaos, New York's surviving members discover an unexpected ally in Jaran, a young novice in the old magic of her ancestors. She is the only defense New York has against this powerful evil. But to use her magic, she must pay a cruel price. Now, with a ruthless NVA hunter-killer team on New York's trail, and an ancient evil lurking in the dark periphery, it dawns on this handful of survivors that escape has a brutal price. And to pay it, New York must become as inhuman as their demonic pursuer.
