Aug. 5 (UPI) -- Sony Pictures is gearing up for the release of the new film Insidious: Out of the Further.

The studio shared a final trailer for the movie Wednesday featuring The Haunting of Bly Manor actress Amelia Eve.

Insidious: Out of the Further is a sequel to Insidious: The Red Door (2023) and the sixth entry in the Insidious horror franchise created by Leigh Whannell and James Wan.

The new film stars Eve as Gemma, a young mother who discovers she can visit The Further, "the purgatorial realm of lost souls at the heart of the Insidious universe."

"When something evil comes after her, Gemma discovers an ability that changes everything: she doesn't just enter The Further, she can bring what lives there back to the real world. Once the demons realize her power, our world becomes their playground," an official synopsis reads.

Lin Shaye returns as Elise Rainier, with other cast members including Brandon Perea and Maisie Richardson-Sellers.

Insidious: Out of the Further is written and directed by Jacob Chase and produced by Whannell, Wan, Jason Blum and Oren Peli.

The movie opens in theaters Aug. 21.
