The action takes place in the provinces, in the seemingly quiet and idyllic town of Królowy Most, where CBŚ agents bring in gangster Jerzy Czapla, a crown witness in a trial against the mafia. As part of the witness's protection, his name and address were changed: now for the ignorant, Czapla, previously known under the pseudonym Żuraw, is called Bocian and lives in a villa rented to him. The details of the case are known only to the police commander, who, incidentally, is still struggling with many other problems: he lacks subordinates, although he has just been assigned to the Queen of the Bridge and cannot find a husband. for the daughter of Luśka, who has an illegitimate heir.
