The story of Chelyabinsk shashlik maker Pasha, who, together with his father and son Kostya, went south to inherit half of a winery. The other half belongs to the aesthete winemaker, a fanatic of his craft, Sergey Gordeev, his daughter Oksana and granddaughter Mila. In order to save their common business from collapse, representatives of two different families will have to become partners. But how can they do this when for Sergey wine is art, and for Pasha it is "tasteless sourness"?
