A month after Emma Callan (Elisabeth Moss) and her family move into their perfect Victorian home, she begins seeing ghastly visions of a sinister doppelganger. With no one else witnessing the entity, Emma must face two horrors: she's either losing her mind or haunted by a malevolent spirit bent on destroying anyone who uncovers the dark secrets of The Attic. From the director of Pet Sematary, this is an intense supernatural thriller.
