The project team is looking for hetman's jewels that confirm Ukrainian statehood and refutes the myths about the Cossacks that have been imposed for years. One of the relics that disappeared from Ukraine is the heart of Hetman Kyryl Rozumovsky. During his burial, a unique sacrament was performed with a limited circle of initiates. The heart was taken from the body. In "Treasures of the Nation" Akim Galimov together with the hetman's descendant - Count Gregor Rozumovsky - will try to find the Ukrainian relic and return it to its place.

The creators of the film also set themselves the goal of debunking the myths that distort people's ideas about the heroic era of the Ukrainian Cossacks.
