At loose ends, actor and playboy Julian Marsh (Jake Hoffman) accepts a gig directing a bizarre adaptation of "Hamlet" -- written by a spooky-looking Romanian playwright -- that transforms the bard's classic into a tale about vampires and finding the Holy Grail. Before long, life begins to imitate art and Marsh is up to his neck in problems as, one by one, cast members become actual vampires and take sides in an ancient war of the undead.
