Politseyskoye bratstvo

Ivan Vasilyevich Shavyrin is given a disappointing diagnosis, and he decides to take his own life. But at X-hour, his daughter Nastya returns, who decided to start a career as an investigator in St. Petersburg. She meets a young operative, Nikita, the son of the legendary Colonel Tarasov, who is serving time in a colony for former employees. Tarasov wants to take revenge on the crime boss Garin, who, in his opinion, is guilty of being imprisoned. Nastya and Nikita find out about Tarasov's plans and try to stop him, while simultaneously investigating other cases. Their fathers help them in this, and they, in turn, are Garin and the famous writer Nezabudkin, who fancies himself a cool opera.
