In the Bitovsk police department, usually everything is calm, because Lieutenant Colonel Krucha always keeps his hand on the pulse of the city. This is his city. In it, he was born and raised. Here he knows everyone, here is Stepan Krucha on his land. But no, no, and something out of the ordinary will happen. And again, Stepan Krucha and his operational team - Maxim Botnev and Sasha Grigoryev enter into a confrontation with criminals. A new employee appears in the team. This is analyst Plato Shvedov. A new person is always a new relationship. This is not to say that Stepan Krucha is friendly towards the innovations of this “wise guy” with the strange name of Plato. They have to find a common language throughout the season, to develop new ways of teamwork.
