Katyn (2007)

When the Soviet Union on 17 September 1939 invades Poland, Anna Aleksandrowna leaves her home in Krakow to search for her husband, the Polish captain Andrzej. She finds him together with other officers captured by the Red Army, but some minutes later he is pushed into a train, which will take all the Polish officers to a prison camp in Kozelsk in Russia. Anna and her daughter Nika is now stuck in the Soviet occupied zone, unable to go back to Krakow in the German zone, not until a brave Russian captain helps them to flee. 3 April 1940 Andrzej is transported from the prison camp in Kozelsk to the Katyn Forest, where thousands of Polish officers are killed. In 1943 the Germans capture this area and find the mass graves. 13 April 1943 they start announcing the names of the identified corpses through loudspeakers in Krakow. Anna is happy that Andrzej is not in any of the Katyn lists, which gives her some hope. 18 January 1945 the Red Army liberates Krakow from the Nazis. The Russians start blaming the Katyn Massacre on the Germans, proclaiming that it happened in 1941 instead of 1940. Everybody knows that this isn't true, but those who refuse to accept the Soviet version are imprisoned or killed by the Red Army.
