“Secrets of Great Ukrainians. Andrey Sheptytsky” is a documentary film. Andrey Sheptytsky (1865-1944) was a Metropolitan of Galicia, Archbishop of Lviv, one of the greatest leaders of the Ukrainian Greek Catholic Church and the national movement of the first half of the 20th century. Andrey Sheptytsky was followed by dozens of intelligence agents. A secret document was kept in the Metropolitan’s residence. That document could radically change the history of Ukraine and Eastern Europe.
