A movie scream so piercing, so chilling and so powerful, it will open up another dimension and summon something beyond all imagining . . .

Far from the isolated prairie ranch where they were born, orphaned twins Isabelle and Beatrice Thorn are living a glamorous 1920s Hollywood life as wards of Mr. Cecil, a mysterious and influential director. Isabelle is a silent film starlet, destined for greatness in the very first talking picture—a horror flick that will showcase her famous scream, often seen but never before heard by audiences. Meanwhile, Beatrice spends her days hidden away on the Cecil estate with her books and her insect collection, scarves covering her birthmarks and baldness. But Beatrice's curiosity about Mr. Cecil, the death of her parents, the appearance of scorpion hornets—creatures that should not exist on this earth—and the unsettling fates of two people who visited his estate is getting the better of her, and she's starting to realize the director has truly dark designs for this movie.
