A two part documentary about the first five decades of Russian cinema: from its birth to 1953 - the death of Stalin and the first seedlings of the thaw. The film covers the most important milestones of cinema. Its introduction as a lowbrow entertainment, the impact of WWI and revolutions on the film process. The principal masters - Kuleshov, Vertov, Eisenstein - and their discoveries in film language at the turn of the 1920-30s. The arrival of sound. The evacuation of the Soviet film industry during WWII and the heroic work of the wartime documentary crews. Restricted film production and early signs of the thaw in the late 1940s - early 1950s. Film historians and art critics, directors and screenwriters put the history of cinema in a broader context, considering the path that the country took from Tsarist Russia to the totalitarian state under the rule of Stalin.

Travelogue of two film historians Nikolay Izvolov and Sergey Kapterev who visit world film archives around the globe in search of a lost sound version of one famous Soviet cartoon. It's "The Post" made by Mikhail Tsekhanovsky in 1929 and based on a poem by Samuil Marshak. At first "The Post" has been released in a silent form and later Tsekhanovsky remade it with experimental music and narration by Daniil Kharms. At that moment it was the first Soviet sound cartoon and it was a success all over the world. Russian film studies consider "The Post" to be of great importance and artistic value but unfortunately it's still lost. Only the silent version and the 1964 remake are still known and available.
