Some monsters only exist in nightmares - others exist for real ...While hunting in the Nez Pearce National Forest, Idaho, two men are just about to take a prize-winning shot when their prey unexpectedly bolts. From the forest behind them lunges a huge, horrific creature that crushes one man and tears after the other in a loping mass of rage. Just as he has embarked on a search to find his missing fiancee, Ethan Warner and his partner, Nicola Lopez, are summoned to a meeting with Doug Jarvis of the Defence Intelligence Agency at a research laboratory outside the city. There, they learn that they are being sent north to interview Jesse MacCarthy, a man accused of a double homicide. But all is not as it seems. Jesse swears blind that the other men were killed by a monster. But as Warner and Lopez dig deeper, they uncover a military secret that has been kept under wraps for generations, an experiment that went terribly wrong, and danger lurking in the highest echelons of the US government.
