Unknown Person

Paranormal investigators Ed and Lorraine Warren take on one last terrifying case involving mysterious entities they must confront.

In 1956 France, a priest is violently murdered, and Sister Irene begins to investigate. She once again comes face-to-face with a powerful evil.

Paranormal investigators Ed and Lorraine Warren encounter what would become one of the most sensational cases from their files. The fight for the soul of a young boy 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.
