Four years after the terrifying events at the Saint Cartha monastery, a new wave of brutal and inexplicable murders spreads across Europe, all bearing the unholy signature of a familiar demonic force. Sister Irene, once again portrayed by Taissa Farmiga, is called back into the darkness, her faith tested as she follows a trail of blood that leads to a secluded boarding school in France. There, she reunites with a now-haunted Maurice, played by Jonas Bloquet, who is struggling to contain the evil that followed him from his past. With the aid of a determined novice, Sister Debra (Storm Reid), Irene must confront the ancient and malevolent entity Valak, the demon nun (Bonnie Aarons), in a desperate battle to prevent its terrifying spread into the wider world. Directed by Michael Chaves and conjured from the minds behind The Conjuring universe, this chilling sequel deepens the gothic horror, pitting pure faith against a relentless evil that thrives in the shadows of forgotten places.
