The Nun is a 2018 American gothic supernatural horror film directed by Corin Hardy and written by Gary Dauberman, from a story by Dauberman and James Wan.[2][3] A spin-off of 2016's The Conjuring 2, and the fifth installment in The Conjuring Universe, the film stars Demián Bichir, Taissa Farmiga, and Jonas Bloquet. The plot follows a Roman Catholic priest and a nun in her novitiate as they uncover an unholy secret in 1952 Romania. While it was being produced, the set was blessed by a Roman Catholic clergyman.[4] The Nun was released in the United States on September 7, 2018, by Warner Bros. Pictures. It has grossed over $228 million worldwide and received mixed reviews from critics, with praise for its performances, direction, cinematography, visuals and atmosphere but criticism for its weak narrative and over-reliance on jump-scares. In 1952 Romania, two Roman Catholic nuns living at the Cârța Monastery are attacked by an unseen force when they enter a tunnel to retrieve an ancient Christian relic. The surviving nun, Sister Victoria, flees from the attacker, a demon appearing as a nun, and hangs herself. Her body is discovered by Frenchie, a man from the village who transports supplies to the nuns. The Vatican learns of the incident and summons Father Burke to Rome, where they ask him to travel with Sister Irene, a nun in her novitiate, to Romania in order to investigate the situation. While Sr. Irene is teaching children the relationship between religion and science in a school, her Mother Superior interrupts her and informs her that Burke has arrived in order to request Irene's accompaniment in his trip to Romania. The pair travel to Romania meet with Frenchie, who leads them to the abbey. They discover Victoria's body and remove a key from her corpse. Inside, they encounter the Abbess, who informs them that the nuns observe a period of silence during the night but the two could return the next day, offering lodging at the attached convent. Frenchie is attacked by a demon as he returns to the village, but escapes. Burke tells Irene that a boy he exorcised, Daniel, was fatally injured during the exorcism, and Burke has been saddened by the boy's death with him ever since. Irene reveals that as a girl, she had visions, causing the Church to take an interest in her. Burke is rescued by Irene after being buried alive in the graveyard by the demonic entity. The next day, Irene and Burke return to the abbey, but only Irene can enter as it is cloistered. She meets some of the other nuns and learns that they are praying constantly, swapping in shifts, to keep evil at bay. Sister Oana reveals the abbey's history: it was built as a castle by a duke who was obsessed with the occult. The duke summoned a demonic entity through a rift in the catacombs but was killed by Christian knights, who sealed the rift with an artifact containing the blood of Jesus Christ. The bombings during the Second World War caused the rift to open again, unleashing the entity. Burke identifies the entity as Valak from a book. He discovers the Abbess has been dead all along. Frenchie heads back to the abbey to help Irene and Burke. Irene is attacked by Valak and joins the nuns in desperate prayer to fend off the demon. When the group reunites, Irene discovers that none of the nuns she had seen and talked to were real and she had been praying alone. Irene realizes that Victoria had been the last nun in the abbey and had sacrificed herself to stop Valak from possessing her body and unleashing evil. Theorizing that Valak can only be stopped if they seal the rift with the blood of Christ contained in the reliquary, the trio retrieves the vial with the key Victoria had. Irene then informs Burke that God has called her to make her solemn vows as a nun and asks Burke to elevate her to the status of a professed nun, which he does in the abbey's chapel. After the trio unlocks the tunnel door, Irene being lured into a pentagram and possessed by Valak. Frenchie smears some of the blood of Christ on her face, casting out the demon. Burke is wounded by Daniel's ghost as Valak starts to drown Irene in a flooded chamber. Irene expels the blood of Christ in the demon's face, banishing it as the blood of Christ seals the rift. After Frenchie resuscitates Irene, he reveals his real name is Maurice. Unbeknownst to the others, Maurice has been partially possessed by Valak, as evidenced by an inverted cross on his neck. Twenty years later at a university seminar, Carolyn Perron watches as Ed and Lorraine Warren present footage of their attempt to exorcise a possessed Maurice. Maurice grabs Lorraine, giving her visions of Ed dying, which initiate the Warrens' investigation of the Perron household haunting, as well as their encounter with Valak itself.
