When in 2002 Jedynka presented Krzysztof Lang's TV series "Prawdziwe psy" about the work of police officers from the Capital Police Station, Commissioner Slawomir Opala and Assistant Commissioner Krzysztof Tkaczyk were among the characters in the series. At the time, both were distinguished officers of the Homicide Department with about 10 years of experience. Within a few months of the end of shooting, dramatic changes occurred in their professional and private lives, and both found themselves at a crossroads in life. Convinced that these changes were related to the series, Krzysztof Lang decided to return to his characters to complete the plot devoted to them. The film is thus a kind of epilogue to that series, and at the same time a psychological portrait of the two operational officers. It shows what a great psychological price one pays for practicing this specific profession, if one wants to do it with integrity.
