Marissa Orlock [Teri Copley] and librarian Dexter Ward [Steve Altman] go to Transylvania, she to attend the funeral and will-reading of her dead father Count Orlock and he to retrieve a 200-year overdue book titled "The Book of All Evil." Also arriving at Castle Orlock is Marissa's uncle Lord Byron Orlock [Robert Vaugh], his three adopted daughters Patti, Maxine and Laverne, and Victor Van Helsing [Ace Mask], a friend of the family. What follows is a hodgepdge of events, i.e., Marissa I possesses Marissa II, Lord Byron et al are vampires, Daddy isn't really dead, and the overdue book must be destroyed so that the Lord of Evil isn't unleashed on the world.
