The Nun 3 continues the terrifying saga of the demonic entity Valak within The Conjuring Universe. Set in the late 1960s, the third installment picks up after the chilling events of The Nun 2, expanding the lore surrounding Valak, the evil nun, and how its dark influence continues to spread across Europe.
The film opens with Sister Irene (Taissa Farmiga) once again being drawn into a battle against Valak. After the events of the previous movie, Irene has retreated to a secluded convent, but her peace is shattered when disturbing visions of Valak begin haunting her. At the same time, strange occurrences unfold in a small village in France, where a string of mysterious deaths and terrifying supernatural phenomena are linked to the cursed abbey.
Father Burke (Demian Bichir), thought to have died in the earlier films, re-emerges, revealing that he was saved by a divine intervention and has been investigating the origins of Valak. Together, Sister Irene and Father Burke must travel back to the abbey, where they first encountered the demonic nun. The stakes are higher this time, as Valak’s power has grown stronger and is no longer confined to the abbey—it’s starting to possess anyone in its path.
As they delve deeper into the abbey’s dark history, Irene uncovers an ancient ritual that ties Valak to the founding of the church itself. They realize that Valak is after a relic hidden within the abbey’s catacombs that holds the key to either banishing the demon forever or unleashing its full power.
The climax of the movie takes place in the heart of the abbey, where Irene confronts Valak in a terrifying showdown. Father Burke sacrifices himself to buy Irene enough time to perform the exorcism, but the final moments leave viewers on edge as Valak’s fate remains ambiguous. As the film closes, there are hints that Valak’s presence will continue to haunt the Conjuring Universe in future installments, leaving the door open for even more terrifying encounters.
