As the holiday season approaches, a group of friends spend the weekend in a house in the country. Among them, Lukas, a young popular singer, comes accompanied by Chloé, his unofficial girlfriend, who will quickly arouse the curiosity of others. The evening is festive, but in the early morning the joy of the friendly reunion will quickly change. The night carries its share of secrets.
Unfortunately the movie Derrière la porte is not yet available on HBO Max.
