After credits: "In 1990, Soviet President Gorbachev admitted that the Soviet Union was responsible for the murders of Polish prisoners of war at Katyn in 1940. No one was ever prosecuted. In 2012, declassified documents proved that the U.S. government suppressed information that attested to Soviet guilt. No British government has ever publicly charged the Soviet Union with responsibility for the Katyn Massacre. This film is dedicated to the 22,000 Polish prisoners of war murdered in the Katyn Massacre and to those murdered in the years that followed so that the truth would remain buried forever."
