Ed and Lorraine Warren (Patrick Wilson and Vera Farmiga) are back on the case -- this time investigating the real-life murder trail of Arne Johnson, who claimed he was possessed by a demon when he killed his landlord. "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," says Warner Bros. The movie hits theaters and HBO Max on June 4.
