Sam and Colby's vacation in paradise goes from enchanting, to weird, to deadly, when Trey, an old acquaintance, insists they can't leave without a visit to the legendary Na Pali Coast. It turns out Trey has been living at the infamous Belle Estate, owned by a wealthy and eccentric widow--who locals believe is a witch. The only thing odder than how a twenty-three-year-old college kid from Utah ended up living in a remote and isolated mansion on the North Shore of Kauai is that he is romantically involved with a woman old enough to be their grandmother. Belle Estate's walls hold an eerie sway over all who enter, and a dark, shadowy presence seems to be following them around the grounds. When an unfavorable change of plans forces them to stay overnight, Sam and Colby are in for the most terrifying encounter of their lives.
