A joint team of Croatian and Czech police officers solves both minor and major crimes on the Adriatic Riviera and gradually unravels the mystery of the death of the partner of one of them.
After the bad outcome of the criminal operation in Lenin Park, Taras decides on a new career path, private detective. First, it is rented by Klara Zupet, a wealthy daughter from Ljubljana. She wants Taras to investigate the new wife of her rich father, the influential entrepreneur Zupet, as she is convinced that she is only with him for self-interest.
In the middle of a hot summer, a homeless woman is murdered in the centre of Ljubljana. At least as much as her death is troubled by the fact that the murder took place in a park right next to the General Police Administration. In addition to Taras's and Tina's relationship, resentment is being drawn from the events at Lake Bohinj over Taras' treatment of the spoiled son of an influential man, so the head of Drvarič assigns the management of the case to Tini instead of Taras. The start of the investigation is not the most promising, as none of the occupants of the park detected anything unusual, even though the windows look out of all the apartments. Yet a criminal investigation reveals that one of them wasn't the most honest.
