Zuid-Amerika, 1919. Op een magische plek bij een imposante waterval richt Julia, de vrouw van een landeigenaar, een smeekbede tot de Iguazú, de mythische moeder van dag en nacht. Julia's dienstbode heeft gewaarschuwd dat dit volgens de oorspronkelijke bevolking streng verboden is. Desondanks doet zij het en zo komt Julia's doodgeboren zoontje weer tot leven – maar hij is niet de enige die terugkeert. De prijs blijkt hoog en doet twee werelden kantelen. Aan de ene kant die van de Europese veroveraars en hun priester, aan de andere kant die van de uitgebuite of gedode Guaraní's (indianen).
Nee, helaas is Los que vuelven nog niet beschikbaar op Netflix in Nederland.
