The Yamuna is the most sacred river in India and for twenty years the most polluted in the country. All the sewers of New Delhi flow into it, creating an immense ecological disaster. Yet thousands of the country's poorest Indians live freely around it. Their names are Augustin, Tulsiram, Kishori, Hari… They were able to invent their own models of adaptation with faith and determination. While the Indian state has always neglected its banks, they are today coveted by numerous real estate developers aided by corrupt politicians. In this new context, the inhabitants of Yamuna must perpetuate their belief while amplifying their spirit of resistance to continue living on their land.
