What do folklore, black metal and zombies have in common?

Ivana Slabáková, guru of Moravian brass band, announces a historical event - the discovery of the Mikulčice Manuscript, which reveals the historical significance of the Great Moravian Empire. Slabáková brings together Moravian patriots, a brass band, a clerofascist, a Brno Satanist and a group of retired amateur musicians to celebrate this sensation with a spectacular Moravian musical. In Rohatec, the heart of Moravian Slovácko region, a great Moravian drama is being diligently rehearsed, but it brings back to life the dead from the Old Slavic burial grounds. But even in the epic clash of cultures, the brass band continues to play in Moravia, zombies trim the vineyard and hope for a better harvest next year.
