An ambitious professor of psychiatry, Viktor Meshchersky, conducts a dangerous psychological experiment in which, under false pretenses, he locks victims and their abusers in the basement, hiding his true goals. The subsequent investigation will reveal the real motives of the professor, and will tie together the confusing stories of all participants in the cruel experiment.

Ira is a wayward 30―year-old Muscovite who does not recognize the rules and principles of modern society. Throughout the season, she easily breaks the fourth wall and openly discusses with the viewer everything that worries her. Topics for reflection and self-reflection are completely different: from mortgages and a night run to the refrigerator to cleaning an apartment and the impact of female pads on the seal population. And the seals would be fine. Ira's personal life is not all right either. She is dating hysterical screenwriter Sergei, but the explosive nature of the woman does not allow them to be together all the time, so the couple regularly quarrels.
