In 1920, the Russian writer Isaac Babel reports on a Red Cavalry campaign in Poland. In 1936, Stalin's NKVD chief Nicolai Yezhov unleashes the Great Purge. In 1989, a mysterious KGB agent spying on a woman in Dresden falls in love. In 2010, an aircraft carrying most of the Polish government crashes near the Russian city of Smolensk... This darkly comic fantasia on Russian themes explores the blurred lines between lies, fiction and conspiracy theories, as it tracks back and forth across 90 years of Soviet and post-Soviet history in search of the genesis of the post-truth world.
