In “The Nun II,” directed by Michael Chaves, the narrative resumes in 1956 France, four years after the events at Saint Cartha’s monastery. Sister Irene, now residing in an Italian convent, is dispatched by the Vatican to investigate a series of mysterious deaths across Europe, all linked to the malevolent demon Valak. Her investigation leads her to a boarding school in Tarascon, where she reunites with Maurice, who has been unknowingly possessed by Valak. As sinister occurrences escalate, Sister Irene, alongside novice Sister Debra, uncovers a connection to Saint Lucy’s relics, which hold the key to vanquishing the demon. The film delves into themes of faith, heritage, and the enduring battle between good and evil, delivering a suspenseful and chilling addition to “The Conjuring” universe.
