The young and zealous opera Titov unwittingly disrupts the operation of the department for combating drug trafficking. By chance, he wounds one of the employees of the “outdoor” Lookout, and brings his partner to dismissal. As punishment for the failure of the operation, Titov is transferred to the OPU — the operational search department, the “outdoor”, and appointed a partner of the Lookout. He is a professional in his field and does everything according to the textbook, which cannot be said about Titov. By chance, typical antagonists by nature and lifestyle are forced to be side by side almost 24 hours a day. Therefore, each surveillance of the partners turns into a cavalcade of events, as a result of which the crime is solved.
