On their drive home, John and his sister, Anna, get into an accident after a horrifying creature jumps out in front of their truck. In order to protect her wounded brother, Anna draws the beast into the woods away from the crash, hoping to at least give John the chance to survive. John regains consciousness just in time to witness Anna make the ultimate sacrifice for him. 

He is left heartbroken and alone. The wounds he sustained have robbed him of the ability to speak. With a debt to repay his sister, John constructs a trap and sets a plan in motion to capture the beast before it can harm another soul.
