Blood Lake

A septet of friends (Andy, Roger, Tricia, Max, Nell, Charlotte and Nicole) travel to a cluster of lakeside cabins, where they unearth a "blood book" that tells the story of Preacher Jacob, a priest who took over the nearby town's congregation in 1896. Jacob had his followers commit mass suicide under the belief that he could resurrect them as a new, perfect race enlightened by their deaths. Max and Nell go off to have sex, but before they do so Max skims the blood book and reads an incantation aloud, summoning the homicidal spirit of Preacher Jacob.
