Enkele maanden na de invasie van de Nazi's in Polen in 1939 werden zo'n 15.000 Poolse krijgsgevangenen vermoord door de Sovjet geheime dienst in een Westelijk gebied van de Sovjet-Unie. De Nazi's ontdekten de massagraven in 1943 tijdens hun tocht door Rusland en wezen onmiddellijk naar de Sovjets, maar die gaven de schuld weer aan de Nazi's. De Geallieerden besloten ondertussen hun ogen te sluiten voor het hele geval. Het verhaal van deze film volgt in het bijzonder de achtergebleven vrouwen en familie van de slachtoffers, die decennialang in onzekerheid bleven over wat het lot van hun geliefden is geweest.
Nee, helaas is Katyń nog niet beschikbaar op Netflix in Nederland.
