A group of Serbian socialists prepares for the war in a surreal underground filled by parties, tragedies, love and hate.

This movie reflects the history of Yugoslavia since the beginning of WWII (and similar to all ex-communist countries) to the last horrible events in Balcanian countries. Behind the comedy is hidden the pain of whole generations, which have suffered WWII, The Cold War, the war in Yugoslavia, the communism, the treachery of their own leadership, the fall. The film shows us the reality, as seen by those who feel unlimited love for their country and culture. Marko and Blacky represent the true leaders of the country, the soul of the nation and not without controversies. Once Upon A Time There Was A Country is an extended TV version of Emir Kusturica's Palme d'Or winning Underground.

After the NATO bombing of Yugoslavia in 1999, the Yugoslav army pulls out of Kosovo region, leaving Serbian people at the mercy of the Albanian UCK. A small band of soldiers must take over the Slatina airport, and hold it until the Russian peacekeepers arrive.
