10-year-old Vladik is a genius of neural networks and a master at getting rid of nannies. When his mother urgently needs to go on a business trip, he has to go to the village to visit his grandfather, whom he has never seen in his life. Vladik dreams of returning to the city and getting into an important IT competition, and his grandfather has no intention of following his lead. Each of them is sure that they can easily outsmart the other, but this meeting will change them both.

Max, an ordinary schoolboy with somewhat unusual parents, finds himself in a village for winter break, against his will. In the village, he encounters a dish that's familiar to the locals but new to him - potato pancakes. The boys, along with their cousin, decide to start a business: they convert an old UAZ into a food truck and sell potato pancakes. But how can you tackle adult problems when you're still a child yourself?
