Here is the basic plot synopsis from the film's official website:
A disparate group of young urban offenders and their care workers embark on a community service weekend in the strange, remote Yorkshire village of Mortlake, which prides on keeping itself to itself. A minor incident with some local inbred youths rapidly escalates into a blood-soaked, deliriously warped nightmare for all involved.
This UK feature has no U.S. release date yet, but I'm sure we will see it over here before too long.
