Since the 1950s, French employers have resorted to the massive importation of Maghreb workers. Paradoxically, few historians have analyzed this period of « proletarianization » of an entire population. In this film project, Ariane Chemin and Frédéric Laffont are following in the footsteps of the 78,000 Moroccans recruited, for the Houillères du Nord Pas-de-Calais, by a former soldier, Félix Mora. Through the footsteps of this character responsible for the arrival of all these workers, the film wishes to tell how these immigrants felt welcomed and watched.

Sharing the stories of these Moroccans also means creating a link between the generations. This aspect of our history deserves to be part of our collective memory and it is ultimately through the past, the narratives and the imaginations that it can be built and passed on to future generations.
