Titov, a young and zealous cop, unwittingly disrupts the operation of the department for combating drug trafficking. By chance, he injures one of Shukher's "outdoor" employees, and brings his partner to dismissal. As punishment for the failure of the operation, Titov is transferred to the OPU - the operational search department, "outdoor", and appointed as Shukher's partner. He is a professional in his field and does everything like a textbook, which cannot be said about Titov. By chance, typical antagonists in character and lifestyle are forced to be side by side for almost 24 hours a day. Therefore, each external observation of partners turns into a cavalcade of events, as a result of which the crime is revealed.
