For Halloween 1992, the BBC decides to broadcast an investigation into the supernatural, hosted by TV chat-show legend Michael Parkinson. Parky (assisted by Mike Smith, Sarah Greene & Craig Charles) and a camera crew attempt to discover the truth behind the most haunted house in Britain. This ground-breaking live television experiment does not go as planned, however.

Two decades after its unprecedented television broadcast, the cast, crew and fans of the notorious BBC 'Halloween Hoax' Ghostwatch look back at the show's unique production and legendary aftermath in this brand-new retrospective documentary. Includes never-before-seen material and interviews!
