In “The Nun” (2018), a priest with a troubled history and a young novitiate are dispatched to investigate the tragic suicide of a nun at a remote abbey in Romania. As they delve deeper, they uncover a sinister secret harbored by the cloistered order. Confronted by a malevolent force in the guise of the demonic nun from “The Conjuring 2,” they must brave not only physical dangers but also spiritual perils as they confront evil in its most terrifying form. The abbey transforms into a nightmarish battleground where the battle between the living and the damned unfolds with chilling intensity.
