Zhenya's parents, Masha and Maxim, are going to Holland for work, and for a long time. Masha is to spend the summer in Kuchugury, in the country house of her grandfather Ivan and grandmother Valentina. As the pedagogical confrontation continues, the Kovalovs immediately appear in Kuchugury under two more or less decent pretexts: first, they have never visited their in-laws; second, Zhenya needs to be prepared for admission to the lyceum. The following month can hardly be called a rural idyll, but Zhenya will find his first true friend, the refined Kovalyovs will comprehend the charms of rural life, meet the unbearably colourful Mitya, and appreciate the sincerity and openness of the villagers.
On the first day of school, both families go to the Kovalyovs, where the Budkos find themselves in the strange and uncomfortable, but fascinating and charming atmosphere of the big city. But the most interesting thing is that as a result of numerous rural and urban adventures and twists and turns, quarrels and reconciliations, unexpected alliances and amazing revelations, the Budkos and Kovalyovs begin to feel like one big family for the first time.
