The Conjuring 2 (2016)

In 1976, paranormal investigators Ed and Lorraine Warren investigate the Amityville murders at the Amityville house, to determine if a demonic presence was truly responsible for Ronald DeFeo Jr. killing his entire family on November 13, 1974, and the subsequent haunting incident involving the Lutz family. During a seance, Lorraine is drawn into a vision where she encounters a demonic nun figure and witnesses Ed being impaled.

One year later, the Hodgson family begins to experience strange occurrences in their home in the London borough of Enfield after Janet, the second-oldest of four children, plays with a ouija board. Janet sleepwalks and converses with the entity of an angry elderly man. When the media attempts to interview the family, Janet is possessed by the elderly man, Bill Wilkins, who previously lived and died in the house. The Warrens are requested to prove whether Janet's demonic possession is a hoax. Lorraine, fearful that her vision of Ed's death may become reality, has another vision of the demonic nun in which the demon says its name. She scratches the name into her Bible in a trance.

While staying at the Hodgson residence, Ed and Lorraine consult other paranormal investigators, including Maurice Grosse and Anita Gregory, on the legitimacy of the case. Gregory presents video evidence of Janet wrecking the kitchen intentionally, thereby discrediting the haunting. Unsure of whether to believe the haunting is real or the family is lying for fame, Ed and Lorraine leave, only to soon discover that Wilkins' spirit is only a pawn being manipulated by the true demon, the nun, who is seeking to break Janet's will. Lorraine's abilities had been blocked by the nun, preventing her from grasping the truth of Janet's possession.

The couple quickly returns to the Hodgson residence and finds Janet possessed, standing at the window, ready to commit suicide. Ed grabs Janet but is close to falling. Lightning strikes the tree in the yard, turning it into the stump that impaled Ed in Lorraine's vision. Lorraine finds the Bible where she wrote the demon's name – Valak. She addresses the demon by its name, gaining dominion over it and successfully condemning it back to Hell. Janet is freed of her possession, and Lorraine pulls her and Ed to safety.

After returning home, Ed adds an item to his and Lorraine's collection – a haunted "Crooked Man" zoetrope toy owned by Peggy's youngest child – placing it beside April Perron's music box and the Annabelle doll.
