Quick recap
Rhode Island, 1971. Roger and Carolyn Perron move their five daughters into a farmhouse. The dog dies, the clocks stop at 3:07 and the girls are attacked. Investigators Ed and Lorraine Warren learn the house belonged to Bathsheba, a witch who sacrificed her child and cursed anyone who lived there. Before the Church can approve an exorcism, Bathsheba possesses Carolyn, who tries to kill two of her daughters. Ed performs the exorcism himself, and Lorraine brings Carolyn back with a happy family memory. The Perrons are saved. At home, the Warrens' daughter Judy is fine, and the house's music box goes into the artifact room.
