In the middle of a hot summer, a homeless woman is murdered in the center of Ljubljana. At least as much as her death is the fact that the murder took place in a park right next to the General Police Department.

In addition to Tarasov's and Tina's relationship, the incident at Lake Bohinj has also led to resentment over Tarasov's treatment of the spoiled son of an influential person, so boss Drvarič assigns Tina to manage the case instead of Taras. The beginning of the investigation is not the most promising, as none of the residents near the park noticed anything unusual, even though all the apartments have windows overlooking the park. However, the criminal investigation reveals that one of them was not the most sincere.

At night, another murder occurs in Ljubljana on Metelkova. This time, the victim is a same-sex rights activist who has a studio at Metel's studio. The detail, which was also seen at the scene of the park's murder, lists the criminals as being connected, and the obstacles they face in carrying out official procedures on suspicion of a politically sensitive matter. Taras takes an alternative route and starts looking for information from old colleagues from intelligence circles who direct him to the "underworld."

A new day brings another death toll. This time in a block by the park. A criminal investigation suggests that one of the witnesses is on her own. However, a renewed informative conversation with a shocked neighbour reveals that the occupants of the block are more interconnected than they were initially willing to say. A closely guarded family secret that comes out in combination with the psychological gripes of the experienced criminal Taras becomes the key to resolving the case, albeit almost at the cost of Tina's life.
