It's a classic English Christmas in the countryside -- snow on the ground, turkey in the oven, the laughter of frolicking children -- until the fun and games take a dark and deadly turn. Is something in the woods spurring the kids to murder? And why are grown-ups always the last to notice when things go horribly awry? There are no easy answers in this nasty little horror flick, but you'll never see Christmas the same way again.
