Mamadou Ba is a public writer. Twice a week, he works in a neighbourhood house in Montreuil. There, we meet a father who would like to have a more decent home, a dismissed worker, an undocumented person, an application for naturalization, etc. The list is long. Through these exchanges, Mamadou’s portrait emerges through his job, which he considers more like a mission: to help his immigrant brothers and sisters with their administrative procedures. By following Mamadou, over time, I wanted to rediscover Montreuil, where I live, through my neighbours, both so close and so far from me. Original version with English subtitles
