Two children, one in Spain and the other in England, are terrorized by a hooded, faceless phantom that has seemingly sprung from the pages of the horror stories they wrote. The creature, called Hollow Face, appears nightly above the bed of young Juan (Izán Corchero), leading his mother to seek help from a priest (Daniel Brühl). Meanwhile, British girl Mia (Ella Purnell) watches as Hollow Face creeps out of her closet and attacks, while her father (Clive Owen) is helpless to defend her.
