Teenager Janice Crogan finds a diary belonging to a previous owner of Beast House, a local tourist attraction in the girl's hometown of Malcasa Point, where numerous gruesome murders have allegedly taken place. The journal features lurid sex scenes between the beast and its author, the house's prior owner. Janice sends an excerpt from the book to famed (fictitious) author Gorman Hardy, who decides to travel to Malcasa Point, along with an accomplice named Brian Blake, in order to steal the book and publish it himself.
