So as a surprise for his eighteenth birthday, his friends take him to the setting for the films, a creepy abandoned house. What starts out as a fun and innocent dream come true quickly turns into a deadly nightmare as they're hunted by a group of role-players who are taking their game too far. The horror co-stars Mathieu Berger, Thalia Besson, and Yann Mendy.
