Director’s brother, Mustapha, disappeared for almost one year. He cut any contact with us, his family that lived then in fear and distress. One evening, after his long absence, the mother received a phone call. He had settled down in the Madrasa Nahlia, a Koranic school of religious teaching in the mountains, 90 km from Marrakech. Through a monologue in the form of a letter, the director dialogues with his brother, remembering their childhood and observing the simplicity, austerity and serenity of the madrasa.
