The Conjuring 2

In 1977 Enfield, the paranormal investigators, Lorraine and Ed Warren, travel to London to help the Hodgsons. After sensing her daughter to be possessed, and her four children haunted by supernatural happenings, Peggy Hodgson asks for help when a malicious entity takes possession of the second eldest child, Janet. However, there's something more threatening, not only for the inhabitants but also for the investigator-couple; something that they couldn't even imagine.
