‘Behind the Wall’ is the story of Nadia, an over-protected five-year-old girl who lives in a Casablanca slum separated from the rest of the city by the wall that surrounds it. She is about to start attending school, which proves to be an upheaval for her parents, and especially for Souad, her mother. Souad remains calm as long as Nadia stays within the shantytown walls, but her serenity evaporates once Nadia transcends the slum’s borders. Then one day, the municipality starts painting this wall. Why this sudden interest?
