 The BBC gives over a whole evening to an  investigation into the supernatural . Four respected presenters and a camera crew attempt to discover the truth behind  The most haunted house in Britain , expecting a light-hearted scare or two and probably the uncovering of a hoax. They think they are in control of the situation. They think they are safe. The viewers settle down and decide to watch  for a laugh . Ninety minutes later the BBC, and the country, was changed, and the consequences are still felt today.
