Zofia Justyńska

Olga, a student who is awkward in life and emotionally, moves into her grandmother's apartment. Initially, she sees her fate as a loser - her roommate gets on her nerves, and the housing estate she knows from childhood seems to be a depressing place. A chance visit to the local bar makes her realize that the estate is inhabited by a strange but fascinating community.

The series follows the investigations of Inspector Marek Bromski (Jakub Wesołowski), his adopted German Shepherd Alex, and members of the Łódź police homicide squad. Based on the Austrian–Italian series, Kommissar Rex.
