A group of childhood friends get together for one of their kids birthday parties in Dublin. The next morning they wake up in a forest in the middle of nowhere being hunted down one by one by a masked serial killer.

In a small town in Ireland childhood friends Fionn, Scott and Paul come across an envelope full of money. They do what any group of "Lads" would do and spend all of the money on pints, smokes, chips and drugs. After spending all of the money in 2 weeks the lads find out that the money belongs to dangerous gangsters who want their money back. The lads must fight for survival and do what ever it takes to get the money back or it will be the last time any of them have a few pints together.
