In the small town of Green Hollow, New York, the Lockley Arms hotel stands as the meeting place for a coven of witches. When the hotel's owners perish in a mysterious car accident, the coven's leader searches for suitable replacements, for the coven membership must equal 13. The teenage twins who live across the street from the hotel volunteer to join the witches's circle. But during their apprenticeship, an evil force kidnaps several of the town's little boys, and the coven must pool its power to combat this sinister threat.
