A camping trip seems like the perfect way for a group of friends to spend a vacation they will never forget. Unfortunately, no one will be left alive to remember the trip! Something lurks in these barren woods, something more insane than a chainsaw-wielding psycho, something more brutal than machete swinging mama's boy and more savage than a tribe of flesh-eating cannibals. There's a LOONY loose!

Steve Coogan plays Tommy Saxondale: an ex-roadie with anger management issues and a pest-control business. Tommy is a little arrogant, a little egotistical and feels the world owes him more respect than it typically shows him. He has an assistant named Raymond who lives in a spare room in Tommy's house, a live-in girlfriend named Magz who owns a T-shirt business, and a receptionist named Vicky who has a tendency to drive him up the wall.
