With The Conjuring 2 a month away, Warner Bros. Pictures rolls out a featurette about the true life story behind the film. In the clip, the real Lorraine Warren speaks about the haunting of a council house in North London during the late 1970s.

The supernatural thriller brings to the screen another real case from the files of renowned demonologists, Ed and Lorraine Warren. Vera Farmiga and Patrick Wilson reprise their roles as the duo, who travels to London to help a single mother raising four children alone in a house plagued by malicious spirits.

The Conjuring 2 hits theaters June 10.
