1956 – France. A priest is murdered. An evil is spreading. The sequel to the worldwide smash hit follows Sister Irene as she once again comes face-to-face with Valak, the demon nun.

A chilling story of terror, murder and unknown evil that shocked even experienced real-life paranormal investigators Ed and Lorraine Warren. One of the most sensational cases from their files, it starts with a fight for the soul of a young boy, then takes them beyond anything they'd ever seen before, to mark the first time in U.S. history that a murder suspect would claim demonic possession as a defense.

Ignoring the eerie warning of a troubled mother suspected of child endangerment, a social worker and her own small kids are soon drawn into a frightening supernatural realm. Their only hope to survive La Llorona's deadly wrath may be a disillusioned priest and the mysticism he practices to keep evil at bay, on the fringes where fear and faith collide.
