Down in the tube station at midnight… Kate falls asleep while waiting for the last train and awakens to find the station deserted and locked up for the night. To cap it all off, Kate has been followed by a sleazy lothario whose atavistic advances she had spurned at a party earlier in the evening. Things look bleak when it becomes clear that not only is her suitor a proponent of the ‘no means yes' school of female psychology but there is something else lurking about in subterranean London, something not entirely human with a penchant for large knives. Bristol boy Christopher Smith has given us a slick, sick and scary edition to the horror genre that while being far from a classic is still head and shoulders above most mainstream efforts.
