A group of graduate students get more than they bargained for while searching for the legendary Bigfoot. Not only is he real, but there's something far more evil lurking in the shadows, the Wendigo.
Based on real events, the story follows a father and son (Offerman and Tremblay) who identify as Sovereign Citizens, a group of anti-government extremists, as they venture across the country and find themselves in a standoff with a chief of police (Dennis Quaid) that sets off an intense manhunt with tragic consequences.
