When M. J. Holliday and her friends travel to Scotland to film the first installment of their new cable TV show, "Ghoul Getters," they find plenty of spooky action in a series of supposedly haunted caverns. But then they discover the body of a maintenance worker, and the cause of death is reminiscent of an old legend: Centuries ago, a mob of angry townsfolk chased a witch, her lover, and her five sisters into the caverns and killed them one by one.
