Presented by the Grave’Side Family association, De Thônex à Madagascar chronicles a year of local mobilisation and a solidarity trip to Ambohimanatrika. In September 2025 fifteen young people from Thônex travelled to Madagascar to help build a village water network. The film follows their collective effort with documentary immediacy, intimate portraits and a focus on youth-driven commitment. It explores themes of solidarity, responsibility and cross-cultural exchange, rendered in a warm, humanist register that highlights labour, landscape and the emotional bonds formed along the journey.
