The Perron family has been silent about the horrifying things they apparently witnessed in their house decades ago.
But now that there's a movie being made about their story, they've decided to speak up.
Hear from the real Perron family in the new trailer for The Conjuring, which is based on their lives.
Vera Farmiga and Patrick Wilson star as the Warrens, a pair of paranormal investigators who are called upon to study the Perron family's supposedly haunted home.
What they find is one of the most terrifying demonic presences they've ever faced.
Lili Taylor, Ron Livingston, Mackenzie Foy, Shannon Kook, Joey King, Hayley McFarland, Stanley Caswell, John Brotherton, and Steve Coulter also star.
The Conjuring is directed by James Wan, and premieres July 19.
