Four young offenders – Tim, Sam, Dwight, Zeb – and their caretakers – Kate and Jeff – travel to a Yorkshire village called Mortlake to do community service, staying in a little cottage. On their first day they decide to have a drink at the local pub where they meet Jim, the bartender. The next day they go salvage abandoned trains where Tim and Sam are attacked by three inbreds. Jeff tries to scare them away but falls on a metal shard, cutting open his femoral artery.
