Beautiful, rustic Blue John Farm in northern England hides an evil secret; a gruesome curse that has terrorized the family of Ian James for 450 years. It has now given him less than a year to live. San Francisco homicide inspector Dean McKenna travels to the James home to help his old college friend defeat it before it destroys more lives. He bring along forensic photographer Carly Herrick, who has an unusual talent for capturing spirit activity on camera. The ancient curse turns out to be more of a challenge than any of them suspected, and it's a rush against time to free the James family from the horror that has stalked them for centuries.
