Sister Irene faces demonic nun Valak once again to protect the vulnerable
Sister Irene, who had bravely investigated the demonic entity named Valak during a frightening incident at a Romanian monastery four years prior, embarks on another mission to confront the same demon. In 1956, she travels to France and learns about a priest who was murdered. With determination, Sister Irene prepares to confront Valak again, an evil nun who exploits the vulnerable and fearful by taking control of their bodies. Her main objective is to shield those who are at high risk of being possessed by this powerful evil force, which she has witnessed firsthand.
