Witchery

Gary (David Hasselhoff) and his gal pal Linda (Catherine Hickland) visit an island off the coast of Massachusetts where a haunted resort hotel looms to do research on witchcraft. They're joined by the Brooks family (including a pregnant Linda Blair), prospective buyers of the property. When a violent storm prevents them from leaving the island, they're forced to endure the vengeful wrath of an evil witch who won't quit until every last one of them dies a horrible death!
