"Vaska" is the affectionate nickname for Vasilievskiy Island in St. Petersburg. Houses from past centuries stand next to new buildings, fashionable boutiques stand next to archaic flea markets, and unique people live in this unique place. One of them is Colonel Aleksandr Petrovich Emelin, head of the criminal investigation department of the Vasileostrovskiy district, who is also the acting head of the entire police department. After another successful operation to catch some scoundrels, Emelin learns from a comrade that an order has been signed at the Main Directorate, and he will be the head of the department without the prefix "acting". On this occasion, Emelin gathers his colleagues from the criminal investigation department in a restaurant, but he is in for a deep disappointment.
