After serving in the army, Lyonka Parasochka got a driver in the fleet, deciding to continue his father's tradition. His mentor was Pyotr Demyanovich Volovich, who knew how to make money by "left trips" and various "operations". Lyonka saw that Volovich lived widely, beyond his means, but at first he somehow did not think about the sources of wealth. Apparently because he was in love with Volovich's daughter Lyusya.

This is a last of 3 movies about 3 friends (the other two are "Kortik" and "Bronzovaya Ptitsa"). The gang has grown up and in this movie they discover and help to stop criminal activity on the factory and in their neighborhood.

Based on the story "Echelon to Germany" by Ivan Shamyakin.

The film takes place in Moscow in 1925, during the New Economic Policy (NEP). The three main characters - Misha, Genka, and Slava - have grown up and become Komsomol members. A murder occurs in their courtyard: engineer Zimin is shot dead at night. The prime suspect turns out to be a local hooligan. But Misha refuses to believe him completely and tries to find evidence on his own.
