However this space has a life of its own, isolated from  the city by a border of gates and authorizations. In Marseille, there are those who work on the port and the others.The myth of an impenetrable world and a protesting working class is nourished on both sides this border.This film proposes a fantastic & dreamlike immersion at  the heart of this slowly disappearing world.
