Get thee to a nunnery! The trailer for The Nun, a distant period prequel to the Conjuring franchise hitting theaters on September 7, is here to terrify the hell out of you. Because, well, there’s no better way to start the day.

On Wednesday, the trailer for The Nun was released by New Line Cinema and Warner Bros. Pictures. Somewhat unusual, the YouTube version of the trailer that asks you to “MAKE SURE YOU WATCH TO THE END.” In a twist, it’s not the end you have to make it to, but the horrifying beginning you need to endure. The “reveal” of the nun at the very start spooked me enough to annoy my coworkers, so be sure you’re wearing headphones.

In The Nun, the mysterious suicide of a young nun in a remote Romanian abbey prompts the Vatican to dispatch a priest and a novitiate nun to investigate, kind of NCIS-style. But when they arrive, they confront an evil force that is actually the same nun from 2016’s The Conjuring 2. The film takes place long before The Conjuring and even before the Annabelle prequels, and The Nun is now the second offshoot coming out of James Wan’s 2013 hit The Conjuring.

The Nun comes from Conjuring producers James Wan (currently hard at work on DC’s Aquaman) and Peter Safran, and is directed by Corin Hardy, who made his debut in 2015’s The Hallow. Among the film’s scars, including Demian Bichir as Father Burke, Taissa Farmiga (American Horror Story) as Sister Irene, and Charlotte Hope (Game of Thrones) as Sister Victoria, Bonnie Aarons returns from The Conjuring 2 as the actual nun the film is named for.

"Oh hey, Karen."

Universal may have tried and failed to win moviegoers with its Dark Universe (pour some out for The Mummy), but Warner Bros. has mastered the obvious secret to creating an ever-evolving interconnected horror franchise: Scaring people.

The Nun hits theaters on September 7.
