In 1982, Professor Matvey Piotrovsky creates a time machine and conducts a scientific experiment, as a result of which one half of his apartment will remain in the eighties, and the other will fall into the Internet era. Nowadays, the living space is shared by businessman Sergey, his wife Svetlana and daughter Kristina. The new neighborhood gives the heroes a lot of inconvenience, because the stratification of two times deprives each of the families of access to the second half of the apartment. The grandson of the scientist Pasha, who waited for 38 years to prevent one tragic event, will also add problems.
