Moscow, year 1982. Scientist Matvey Pyotrovsky creates a time machine and conducts a scientific experiment, which divides the apartment in two parts. It's first part is left in the 80-s with the professor, while the second one is transported to year 2020 to a modern family: businessman Sergey, his wife Svetlana and daughter Kristina. This kind of coliving creates a lot of trouble for everybody, since layering of two times means each of the families has lost access to the other part of the apartment. But problems don't end there: inventor's grandson Pavel, after waiting for 38 years, tries to prevent one tragic incident.

Entering it, they find themselves in a world where the environment and what is happening are indistinguishable from real life.

The legitimate heir to the throne in exile and the son of a murdered rebel — what do they have in common? Everyone has their own goal: one dreams of taking the throne and restoring his family to its former glory, the other - to take revenge on the murderer of his father, who serves the usurpers. Young men enter into a large-scale struggle for power and honor, in which those who seemed to be friends can betray, and former enemies can turn into allies. In order to achieve the goal, both the prince and the rebel's son will have to risk the most valuable and make the main choice in their lives — to go the preordained way or to oppose fate itself.

The action of the film takes place on the territory of the karting track, where Yegor Matveyevich works and lives. One day his grandson Artyom comes to him - a modern teenager.

Artyom and Slava are students of Moscow State University, one is studying at the Faculty of History, the other at the Physics. They have no money, no connections, no relatives, except for grandmothers who regularly send half of their pension, but they have youth, joy in life, a sense of humor and the hope that they will surely “break through” and they will have everything well. In this situation, you can even live on a scholarship. Everything would be fine if the students didn’t have a seemingly simple task in one day: to get 40 thousand rubles in two weeks to participate in the Roscosmos project competition with their own promising development. It would seem ridiculous money for a city like Moscow. But absolutely not funny for poor students - sophomores.
