Górska and Garda receive an unusual case to solve. A young woman undergoing psychiatric treatment told a therapist that she had witnessed a murder. However, she soon changed her mind and stopped the therapy. It turns out that the woman is the daughter of a dangerous criminal, Żurawina - known as a mafia lawyer, whom the Central Bureau of Investigation has been investigating for some time. At the same time, investigators are trying to find out why the girl's partner has disappeared. Over time, a suspicion arises that the boy may have been conducting a private investigation regarding Żurawina.
