Moscow, 31 December 1991: the Red Flag of the Kremlin is pulled down and replaced by the three-coloured banner of Russia, marking the end of the Soviet Union and of its ideologies. Illustrated with testimonies of top protagonists and Mikhail Gorbachev himself, the documentary recounts, day by day, the critical last two years that led to the fall of the largest and one of the most totalitarian empires of the 20th century.
