Colleagues are mentally preparing Maria Pavlovna for an unusual corporate event. Instead of a glass of cognac, bird's milk and everyday conversations, everyone has to be involved in the board game "Mordasia", developed by the historian. And while the math teacher is trying to figure out if the courtesan's card is offensive to her, another performance is being played out at the table, which the teachers don't even know about.

The temporary absence of the director gives Natalia unexpected power. And the first measure she decides to take is to install surveillance cameras, because they have already spent money from the budget on them. But colleagues are ready to defend their independence. Maria Pavlovna makes the first move in this struggle, but she is much more concerned about her granddaughter: Nastya has encountered oddities in Bogdan's behavior.
