The place that used to be known as the "Mexican Niagara", a natural paradise shaped by the Santiago river and the waterfall of "El Salto de Juanacatlán" is now a poisonous place for the community that lives in its bank. With the establishment of an industrial corridor near the city ofGuadalajara in the 70's, the waters became toxic and destructive. Today the Santiago river is one of the most polluted ones in Mexico. While authorities keep ignoring the problem and locals are dying silently and suffering from diseases like cancer, chronic kidney disease, skin diseases and infections among other health problems, Polgovsky focuses on a local family that fights to survive in the ruins of their town.
