David Moreau and Xavier Perud's brief but nastily effective thriller carriers echoes of 'The Blair Witch Project' - the start is all suggestion and fear, with very little seen, and 'Assault on Precinct 13', with a plot centred on an apparently motiveless, but overwhelming, attack on its protagonists. The film is apparently based on a true story, although I doubt that in reality a Transylvanian manor house would really link up to such an extensive collection of sewers and cellars. True or not, it's not really a story about anything; the final revelation, about the identity of the attackers, is shocking but as we don't see anything from their perspective, also limited. Nonetheless, this is a film that will have you flinching in your seat on more than one occasion.
