When Sam and Paige decide to escape the stress of medical school for a romantic getaway in the mountains outside L.A., their four best friends end up tagging along and turning it into a weekend of partying. Little does the group know that their beautiful lodge has a dark history: exactly one year before, the house was the scene of a grisly double murder - and the killer was never caught. Now, as night falls and the group drinks beer by the bonfire, a predator hides in the darkness, watching them all through the crosshairs of a sniper rifle. In an instant, the friends' night of partying turns into a bloody fight for survival.
