A woman shares her bed with her husband-and a ghost who makes advances to her; a man is clutched by a ghostly hand and sees a fire engine drive through his room; a woman is haunted by a presence - sometimes friendly, sometimes not; a boy dabbles with the ouija board and sees the devil. Today, faced with the complexities of modern technological life, people are once again turning towards the mysteries of the occult. The result-an increasing demand for exorcisms and cures performed by churchmen, witches and psychiatrists. Jeremy James has talked to the possessed, clergymen, a white witch, doctors and a ghost hunter to try to find out if there are those haunted from beyond the grave - or if it's all in the mind.
