Manhunt

A bunch of friends are on their summer holidays and are very bored in the home town of Arklow. They have nothing to do and then decide to go out to the forest for a night of drinking and doing drugs. They all then wake up the next morning by them selves all seperated around the forest with numbers on their wrists. They soon realise that they are being killed off one by one and by a masked killer in the woods named "Sean Pearce" and the number that is on their wrist is the number they are going to die by and could one of these friends be Sean Pearce himself ?
