The frightening story of survival premieres next month.

Shudder has released the trailer for THE BOY BEHIND THE DOOR, which becomes exclusively available on the streaming service July 29. David Charbonier and Justin Powell (THE DJINN) scripted and directed the movie, which stars Lonnie Chavis, Ezra Dewey, Kristin Bauer Van Straten, Scott Michael Foster and Micah Hauptman. The synopsis: “A night of unimaginable terror awaits 12-year-old Bobby [Chavis] and his best friend, Kevin [Dewey], when they are abducted on their way home from school. Managing to escape his confines, Bobby navigates the dark halls, praying his presence goes unnoticed as he avoids his captor at every turn. Even worse is the arrival of another stranger, whose mysterious arrangement with the kidnapper may spell certain doom for Kevin. With no means of calling for help and miles of dark country in every direction, Bobby embarks on a rescue mission, determined to get himself and Kevin out alive… or die trying.”
