An innocuous-seeming video-message marks the beginning of a series of disturbing events that rapidly terrorize student Andrea’s everyday life. An apparently invisible figure follows her wherever she goes and turns her existence into a living hell. What she doesn’t know is that some 20 years earlier—and around 10,000km away—Marie and Camila were confronted with the same malicious entity. All were/are plagued by the same sound: a bone-chilling wailing. Elite star Ester Expósito shines in Pedro Martín-Calero’s impressively self-assured feature-film debut: a modern horror tale in the footsteps of It Follows, inspired by the chilling stories of Argentinian writer Mariana Enríquez.
