In the center of the plot is a senior investigator named Masha Shvetsova and her male colleagues. The plot is the most vital, but, like in “Streets of Broken Lanterns,” it is seasoned with a fair amount of humor - otherwise, how can the audience (and the heroes) endure countless morgues, identifications and other “cute” charms of the investigative routine?

The protagonist finds out that some children were left behind in a sinking school, and is slowly driven mad as he tries to save them. A parable on the theme of the Last Judgment, numerous catastrophic events reveal a certain ambiguity in their origins, accompanied by the terrible suspicion that the things going on are some kind of a performance or theatrical production.
