Police captain Pavel Semyonov serves in one of the residential areas of St. Petersburg. Pavel is used to breaking up drunken fights and entering drug dens alone to make another arrest. He knows that if he thinks and argues, he will simply be killed. And he is used to first acting, and then sorting it out, because he really wants to stay alive, because his wife Yulia and son Sasha are waiting for him at home. Risking his life, he saves the daughter of a businessman. In gratitude, Latyshev, the girl's father, facilitates the transfer of Pavel to Nevsky Prospekt, to the very center of the big city, where it is prestigious and profitable to serve ... And soon Pavel begins to suspect that his transfer to the Central District was carried out by Latyshev with some far-reaching plans. And when Pavel goes on the trail of a mysterious killer named Rafael, everything is completely confused. But in a difficult situation, Pavel can always rely on his friends from the sleeping area

The Investigative and Analytical Department (ACS) is headed by Colonel Andrei Gromov. Employees of the department are engaged in the search for criminals and forensic examination. They study evidence, build an evidence base, interview witnesses, and conduct face-to-face interviews in a high-tech office equipped with the latest technology. Agents can find at the crime scene not only fingerprints, but also traces of electronic devices that were in the area at the time of the murder. In this, the ACS staff is assisted by a mobile "Scanner" laboratory with access to cell towers.
