In 2015, the São Francisco River, in Brazil, reached its lowest flow rate in history. The drought and the contamination are made worse by the reckless use of the river water. Facing this scenario, the "vazanteiros" - traditional people who survives by fishing and cultivating on the river banks - who had originally been cast out from Lapinha and Pau Preto, their communities, are now taking back their places. They defend their right to live by the river banks, in harmony with the Old Chico (a nickname for the São Francisco River): they consider themselves to be the guardians of the river.
