Mary is a nurse in Mayotte. One night on the beach, a young woman rescued from a "kwassa" (a clandestine boat from the Comoros), entrusts her baby to her. The child has eyes of different colours, and according to some beliefs, this anomaly is associated with the devil. Mary takes the child in and decides to raise him alone, naming him Moses. There he lives as a pampered and protected child until the age of 13, when Mary dies suddenly. In search of his roots, Moses goes to one of the slums, where dozens of orphans are entirely left to their own devices. There, he meets Bruce, the head of the slum, tyrannical and unpredictable. On this burning island, Moses' destiny is turned upside down.
