Broom Street, an underground railway station with a tragic history and abandoned since the 1950's, is surveyed by a present day maintenance crew. After one of them is seriously injured, claiming to have been pushed by unseen hands, and video footage captures strange light phenomena, two of the crew make contact with a small team of paranormal investigators. Acting without official permission, the paranormal team, including a powerful psychic, are taken down into the eerie dilapidated station, and adjoining tunnels, to conduct an all night investigation. After making a gruesome discovery that horrifies them all, it soon becomes apparent that a dark force is present.
