The film profiles two rivers and a sacred saltwater lagoon system in the indigenous Mixtec, mestizo, and Afro-descendant communities in the Oaxaca's coastal region in Mexico. For indigenous Mixtec communities upstream, the fate of water is in the hands of gods and rain goddesses that dwell in caves and mountains. For mestizo farmers and population in urban centers, everything revolves around water scarcity and pollution. For Afro Mexican fishermen downstream, the crucial issue is the quantity of fish and the complex relationship between river runoff and ocean saltwater.
