Brother and sister, teenagers Savva and Aglaya, live in the city and do what they like most. Savva is a fan of computer games and an eternal fidget. Aglaya is a young genius of science who dreams of making an important discovery. Each has plans for the summer holidays: Savva is going to a games festival, and Aglaya is working on a project at a science camp. But one day, their plans fall apart. Since the guys are always teasing each other, arguing about everything and can't agree on anything, one day a disaster occurs, as a result of which their apartment is simultaneously flooded with water and engulfed in fire. As punishment, the parents send the children to the village to their grandparents. For Savva and Aglaya, this is a nightmare: they are used to food delivery, entertainment, games and the Internet, and in the village they have to get up early, work in the garden, feed for slaughter, go to the bathhouse and a bunch of other village "delights".
