The main characters of the serial are two officers of the criminal investigation department who accidentally became colleagues. But thanks to this fact a rather dramatic story acquires a comedian plot. Medvedev and Burov are absolutely different and the only thing that unites them is their thirst for justice which they uphold in the Criminal and Drugs Investigation Department. Despite their hostility to each other the Head of the Department decides to make them fellow workers. This decision becomes effective for the department as well as for both of them. The situations they get in are sometimes much more dangerous than they can even imagine. Witty dialogues and unhappy Burov's jokes, funny characters, ridiculous situations the characters get in and the style of their communication make this serial comic and fresh. The story becomes spicier when captain Burov falls in love with the daughter of his boss, a very pretty young lady who tries to become independent.
