Synopsis
When a London modeling agency booker dozes off while waiting for the midnight subway train, the subterranean terror that awaits her in the underground tunnels will send her screaming for her life through a dark labyrinth in this horror entry directed by Christopher Smith and starring Run Lola Run's Franka Potente. Awakening to discover that the midnight train has passed and she is locked in the station, Kate (Potente) reluctantly steps onto a mysterious empty train for a ride she will not soon forget. As the train grinds to a stop in the pitch black tunnels of the London Underground, Kate realizes that she is not alone in the darkness and if she has any hope of surviving until dawn she'll have to fight for her life against an unimaginable horror too terrifying for the light of day. ~ Jason Buchanan, All Movie Guide
