Stay on the train...

Mike and his friends have a blast as they celebrate his last night as a bachelor. Little do they know it could be their last day alive. They leave a local nightclub with a group of girls to continue partying at another bar, but a freak thunderstorm forces them to take the subway instead of waiting for a cab. The train stops at an abandoned station. Everyone hops out when Mike’s brother Tony gets into an argument with one of the girls. By the time they realise they are at the wrong station, the train has already left. The gates to the station are locked and there is no way out. The group make their way down the dark subway tunnel where Mike gets the feeling they’re being followed. When they reach the next station and witness a murder, they run back into the tunnels, followed by the subhuman savages that live underneath the city.
