The police station is planning a manhunt for the man responsible for killing a young policeman. The seventh patrol is primarily involved in the case. Meanwhile, a man appears at the reception claiming to have killed someone. Commander Witacki delegates Białach and Góral to check this report first. It turns out that the case happened twenty-five years ago. Apparently, during an argument, the man killed another with a knife and buried him in the park. The police go with the suspect to the place where the body is hidden. Unfortunately, there is no longer a park in the indicated location, but there is a skyscraper with offices there. Meanwhile, the daughter of a self-proclaimed murderer appears at the police station... The police also find a clue that may confirm the crime from the past.
