Activist and social activist Kapitolina Sermyagina is always at the center of events. But now, tired of adventures, she finally got married and built a house in what she thought was a quiet working-class village. Of course, she would happily rush to help anyone. However, Ostap Donyushkin’s night call with a plea for help takes even her by surprise. Ostap has just been shot, and Kapitolina will have to act very quickly, because the criminal has already set off to kill his mother-in-law, wife and little daughter Ksyusha who are still at home. Who needs Ostap and his family? Gloomy loggers competing with the business of the most powerful family in the area? The intelligence services of a neighboring country, in one of whose special forces your mother-in-law once served? Or maybe the killer is haunted by the famous treasure of the Galuchev family, and someone is removing the heirs? Could it be that the prisoners who escaped from the island prison are to blame? Or has the famous Svetloputeysky maniac gone completely wild?
