Determined to keep Annabelle from wreaking more havoc, demonologists Ed (Patrick Wilson) and Lorraine Warren (Vera Farmiga) bring the possessed doll to the locked artifacts room in their home, placing her "safely" behind sacred glass and enlisting a priest's holy blessing. But an unholy night of horror awaits as Annabelle awakens the evil spirits in the room, who all set their sights on a new target--the Warrens' ten-year-old daughter, Judy (Mckenna Grace), and her friends.
