Before she helped the Lambert family, paranormal guru Elise Rainier helped many other tortured souls, including one in her own family home, the setting of the fourth film in the Insidious franchise, The Last Key, and you can watch the official trailer for the James Wan-produced film right now.

"The creative minds behind the hit Insidious trilogy return for Insidious: The Last Key. In the supernatural thriller, which welcomes back franchise standout Lin Shaye as Dr. Elise Rainier, the brilliant parapsychologist faces her most fearsome and personal haunting yet: in her own family home.

The film is written by co-creator Leigh Whannell (Saw), who wrote the trilogy and directed Chapter 3; produced by Insidious regulars Jason Blum (The Purge series, Get Out), Oren Peli (Paranormal Activity) and co-creator James Wan (The Conjuring, Furious 7); and directed by series newcomer Adam Robitel (The Taking of Deborah Logan).

Steven Schneider, Brian Kavanaugh-Jones, Charles Layton, Bailey Conway Anglewicz, Couper Samuelson and Whannell serve as executive producers. Sony Pictures Worldwide Acquisitions is financing Insidious: Chapter 4, and domestic distribution will be handled by Universal Pictures. Sony will handle international distribution."
