The Niger River in Mali crosses a vast plain in the heart of the Sahel. It is a vivid patchwork of canals, rivers, lakes, islands, seas, prairies and flood zones. Throughout this territory, human societies have learned to live together, in a symbiotic relationship with the cycles and movements of the river. During the dry season, as water levels began receding, filmmaker Sylvain L'Esperance followed the people of the delta – artisans, merchants, navigators, herders and fishermen – in search of a human portrait of the river.
