The ‘Conjuring’ universe concludes with ‘Last Rites,’ depicting Ed and Lorraine Warren’s investigation into the Smurl haunting of the 1980s. The Smurl family reported terrifying events, including physical attacks and paranormal phenomena. While the Warrens intervened, skepticism arose, and the family attributed the cessation of hauntings to their faith, despite the film taking creative liberties with the true story.
