A man appears at the police station to report the theft of a hunting rifle. The case is being handled by staff midshipmen Mróz and Korwicki from the sixth patrol. The police first check whether the man has a firearms license. The police and a technician go to the scene of the incident. It turns out that the theft was made from a home safe, but there are no signs of forced entry. Suspicion falls on the injured person's immediate family. Neither his wife nor his two sons share the head of the family's hunting passion. During the investigation, it turns out that one of the sons of the robbed man did not show up at school and contact with him was lost. The police suspect that this may be the main clue in this investigation. Meanwhile, Igor returns home. Iza appears with Igor in Marek's apartment and decides to take care of her son.
