On August 11,1999, Druids from all over Europe congregated in Cornwall, England, for the last solar eclipse of the millenium. Some believed that the spirit of Merlin would return that day to be reincarnated. Merlin, a Druid, had died near there during a solar eclipse in 450 AD.
Phillip and Elizabeth Poole had their baby in Cornwall that day, the only baby to be born during the total darkness of the eclipse. They did not question the significance of these circumstances until their son, Morgan, was fourteen. Then, while undergoing treatment for leukemia, he developed disturbing, recurrent dreams. In these dreams, Morgan guarded a basement door, trying to prevent a man in that basement from getting out.
When the Pooles discovered that this dream represented the emergence of a foreign spirit within their son, they consulted with both conventional and paranormal spiritual advisors. As the dreams intensified and the spirit grew stronger, so did the efforts of the Pooles to extricate this spirit. After Morgan predicted the grizzly, ritualistic murder of a prominent environmentalist and became a suspect of the crime himself, the Pooles reached deeper into the paranormal underground for help. This triggered a chain of events that led to the climactic ending at Stonehenge, the ancient Druid temple.
