The plot follows a young nun in Romania who, after experiencing demonic possession, seeks help from a priest with a haunted past and a novice on the threshold of her final vows. They uncover an unholy secret: a malevolent force in the form of a demonic nun. To fight the evil, they must uncover the order’s unholy secret—risking not only their lives, but their souls.

The Nun was released in the United States on September 7, 2018, and grossed over $365 million worldwide against a production budget of $22 million. The film received generally unfavorable reviews from critics, who criticized its screenplay and pacing, as well as its reliance on jump scares. Despite an overall negative critical reception, audiences reacted positively to the film, with it eventually becoming one of the highest-grossing entries in the Conjuring film series. A sequel is currently in development.
