What happens when director M. Night Shyamalan (The Sixth Sense, Unbreakable, Signs, The Village, Lady in the Water) teams up with producer Jason Blum (Paranormal Activity, Insidious, Sinister, The Purge)?

The Visit, that’s what. Shyamalan’s next original supernatural film goes a little something like this:

Shyamalan returns to his roots with the terrifying story of a brother and sister who are sent to their grandparents’ remote Pennsylvania farm for a weeklong trip. Once the children discover that the elderly couple is involved in something deeply disturbing, they see their chances of getting back home are growing smaller every day.

Let’s just say these aren’t your typical grandparents–unless your Grandma and Grandpa are seemingly possessed by otherworldly, decidedly demonic creatures.

With The Visit, Shyamalan is embracing Blum’s tried-and-true “found footage” shooting technique; Paranormal Activity and its many sequels have proven that even dirt-cheap horror flicks can be thrilling and quite lucrative. Though the acclaimed director has shot some duds as of late (read: The Happening, After Earth), this inevitable collaboration between Shyamalan and Blum is just tantalizing enough to warrant a look-see. Shyamalan is known for his twist endings that turn all of the events proceeding it on its head, and I can only imagine what he’s cooked up in Blumhouse Productions’ latest.

The Visit opens September 11.
