Based on the experience of living in a shared house and sharing domestic space, the film aims to explore the link between rules, territory and group. The film will be structured like the architecture of a house, the camera will move from room to room, from character to character : from the basement to the roof, each room is conceived as a different chapter, like a still life painting or a poetic game. But if the camera remains confined to the house, questions break out and go to visit architects, lawyers, job seekers, musicians, … asking the same question to all : why and when do we need rules?
