In the villages of Senegal, where oral traditions can constitute an integral element in development projects, the wandering poet, Thierno Seydou Sall, introduces a new system of social communication with the goal of effecting positive change in the comportments and attitudes of rural populations.Two musicians, encouraged by the power of his pertinent and provocative poetry, help him. It is this man who we follow in his wanderings, in his travels, in his interactions with rural communities.
