They do everything else with sickening panache, but the French have never got to grips with the slasher flick, which makes this back-to-basics horror as unexpected as it is violent. A sexy teen (Cécile De France) is invited to the family home of her best friend (Maïwenn Le Besco) out in the French equivalent of redneck country. She meets mum, dad and little brother, night falls, a rusty old van pulls up outside, a fat bloke gets out and starts graphically raping and killing everyone. No intellectual chit-chat here, then.
