Joseph Mersault (Devon Sawa), his wife Anne (Camille Sullivan), and their daughter Renée (Summer H. Howell) live in the remote wilderness and earn their living as fur trappers. The family struggles to make ends meet and think their prey are being hunted by the return of a rogue wolf. Determined to catch the predator in the act, Joseph leaves his family behind to kill the wolf. But what he finds instead is the dumping grounds of a serial killer deep in the woods and sets bear traps around the bodies as he lies in wait for the predator to return. Anne and Renée grow increasingly anxious during Joseph’s prolonged absence and struggle to survive without him. When they hear a strange noise outside their cabin, Anne hopes it is Joseph but instead finds a man named Lou (Nick Stahl), who has been severely injured and left for dead. Anne and Renée take Lou in and nurse him back to health, thinking he’s fallen victim to the vicious wolf. But the longer Lou stays and Joseph is away, Anne realizes Lou isn’t a victim—he’s the killer Joseph discovered in the woods.
