Ghosts abound in Britain. Thousands of people have seen and heard what they believe to be phantom footsteps, abnormal phenomena, and ghosts of all shapes and sizes, sometimes even moving above ground level. In tonight's documentary Hugh Burnett visits some of the people who have tried to track them down, or heard and seen things they cannot explain. The film ranges from a haunted house, a â haunted inn, even a theatre haunted by a butterfly - to Borley Church where many strange occurrences have been recorded.
