In an old popular neighborhood of Paris, the last factory will disappear, without a noise. Hanging on the facade, the panels of a real estate developer already announce its transformation into a residential building. Behind the walls, the workers are still at work. Their language is created by the sound of the machines. They are there, with their lives, their projects and their dreams. A chorus of neighbors echoes through the street, revealing the dull violence of the changes in the city.
