As this film opens two workers are walking through a London sewer; one of them discovers a collapsed wall. Behind it there is a tunnel he has never seen before... it soon becomes apparent that there is something there. The action then cuts to an office party where Kate, a German woman, rejects the advances of a man named Guy before leaving. She head to Charing Cross tube station but fall asleep on the platform and misses the last train. She is now locked in the apparently empty station. When a train stops she boards. Shortly after it pulls out of the station it stops again. It soon emerges that she is not alone; Guy is on board the train and he attempts to rape her... someone, or something, pulls Guy off her; there is clearly something more dangerous down there. While trying to escape she encounters others in the station... not many of them will survive to the morning.
This is an effective low budget horror movie. The setting is great; both the closes tube station and the sewer tunnels are naturally creepy locations without the added menace of an unknown being that is attacking people. The earlier parts of the film, before we actually see what or who is killing people are perhaps better as what we don't see is usually scarier than what we do. Once we do see the attacker the scares still come, with several quite gory attacks. The explanation as to his origins are perhaps unnecessary but don't detract from the story. Horror fans should certainly enjoy this as once the danger to Kate becomes apparent the tension rarely drops. The cast is solid; most notably Franka Polente, who impresses as Kate. Overall I wouldn't say this is a must see but I'd still say it is well worth watching if you are a horror fan.
