Documentary about unexplained phenomena experienced by staff and passengers on the London Underground network. One billion people a year descend 150 feet below London, to the tunnels and stations of the tube, without a second thought for the thousands of graves, church crypts, and plague pits that the tube has disrupted over its 100 years. Featuring previously unheard accounts from people who work on the network, drivers, station staff and workers.
