During a warm and arid summer, three inseparable teenagers—Dan, Tom, and Victor—seize the opportunity of their last school day to roam the countryside. Their spirits soar when they stumble upon an abandoned film studio, its labyrinth of corridors and rooms inviting exploration. Unbeknownst to them, this newfound playground is a hideout for Isaac and Klarence Shooter, a man and his peculiar son, who are determined to keep the trio from uncovering their sinister secrets. As night descends, the boys return home, only to realize that something has followed them. This night promises to be the longest of their young lives, and the chances of them seeing daylight again are slim.
