Lawyer Đorđe Čogurić and police chief Andrija Kustudić begin to uncover links between the body found by the Sava and the death in Topčider, leading back to the royal court.

Čogurić receives an anonymous letter suggesting that Ilka Marković left a diary in prison. The investigation shifts to the prison archives, where they discover that certain documents vanished just before her death.

Chief Kustudić discovers he is being followed during the investigation. Shadows from the past become increasingly dangerous as it turns out that people from the highest political circles are involved in the murders, desperate to keep the truth about Ilka buried.

The first real fruits of the investigation begin to appear, but at the same time new doubts and mistrust are sown among the main characters. Vida must face an unpleasant reality and grow up quickly, as the family secrets of the elite begin to intertwine with a political conspiracy that threatens the stability of the kingdom itself.

Andrija and Đorđe's investigation becomes increasingly complicated when the clues lead to the hidden societies of the Belgrade elite. The discovery of a secret political club confirms that the murders of a young unknown woman and a descendant of a dynasty were not random, but part of a carefully planned political game. Pressure on the police increases, and the suspects from the Vitković family become increasingly suspicious.
