Chief accountant Porfiry Petrovich Smirnov-Alyansky, who took a good walk on the anniversary of his colleague cashier Ivan Zakharovich Vodnev, climbs into the traffic controller's booth and disrupts traffic on one of the streets of Leningrad.

Fortunately, the young sergeant will soon have an opportunity to prove to others the responsibility and conscientiousness of the police officers.
