The annual meeting of co-owners is the scene where the dramas of which a building is the breeding ground are unraveled. The stake goes well beyond simple "good management" so much the building which shelters passions is impregnated. Under the leadership of Jean-Louis, a cunning and depressed property manager, the co-owners of 28 rue des Oursins clash. A first cleavage separates them: inhabitants of the building or simple holders of a title. Then the dividing lines marry the interests of each other, which are further blurred by the differences of ages, origins, affinities.
