In het Tsjechisch-sprekende Bohemen aan het einde van de 19e eeuw kwamen onderdrukte arbeiders in mijnen en gieterijen in Duitse handen in opstand tegen hun barre arbeidsomstandigheden. De film, gemaakt kort na de Tweede Wereldoorlog toen Tsjechoslowakije ten prooi viel aan het communisme, resoneert met de Tsjechische wrok tegen de Duitse bezetting.
Nee, helaas is Siréna nog niet beschikbaar op Netflix in Nederland.
