Maleficent doll Annabelle is back! On this occasion, the paranormal phenomena triggered by this diabolical doll will directly affect renowned demonologists Lorraine and Ed Warren, as well as their 10-year-old daughter, Judy. Determined to prevent Annabelle from doing more harm, Demonologists Ed and Lorraine Warren take the doll owned in the artifact room of their home, strategically placing it behind a sacred stained glass window. However, a dreadful night is about to begin, as Annabelle awakens the evil spirits in the artifact room, aiming at them with a new target: Warren’s 10-year-old daughter Judy, and his good mother. In the small museum where Warren’s husbands keep the magical artifacts they’ve collected over the years as they fought against the forces of evil, the Annabelle doll begins her macabre plan and unleashes chaos.
