Hoping for an unforgettable birthday, a group of friends sign up for an immersive horror-movie experience that promises to place them inside their own 1980s slasher film. But as the night unfolds, the lines between fiction and reality disappear, and what begins as a game of make-believe soon becomes a desperate fight for survival, where the only way to stay alive is to make it to the final reel.
