Sean, a recently returned veteran, and Mike a hedge fund manager, head out of town to hunt in a closed nature preserve with Mike's wife, Wit - a brainy anesthesiologist - in tow. With Sean unhinged from his stint in the military, and Mike distracted by career ambition, this was not the romantic getaway Wit was hoping for. But soon the trio is threatened by an unseen menace, and the hunters become the hunted. A camping trip in the woods turns into a contest for survival. When the brothers are stalked and ensnared, Wit must unleash her own animal instincts or else end up a trophy.
