In Osijek, an apparently ordinary break-in, at the house of the former public prosecutor Branimir Kovac, reveals more secrets

One girl drowned in the Drava in Osijek, she is very young and no one knows who she is. Police Inspector Kovac is trying to find out if it was an accident or she was killed. Local journalist Stribor is also interested in the case.

A third girl is found dead in Osijek. In Kyiv, Olga and Nikolay search for Viktor, a sleazy photographer who might know where Katya is.

Stribor discovers that the current events in Osijek are connected to the long-hushed-up case. Olga finds out about fake humanitarian organisations drawing in young women.

Vesna and Vladimir find out about two of the victims' criminal and reform-school pasts. Who removed their files and fingerprints from the police database?

Volunteers confirm to Olga that someone is taking women from the centre. Olga tries to persuade Mila to help her, but Mila has demands that must be met first.

A psychiatrist from the Osijek hospital has doubts about chief suspect Kozul's guilt. The police have to release him because of their lack of proof and his partial alibi.

Olga returns to Kyiv to discover the truth about her niece. The police investigation shifts focus to a close associate of Olga's husband.

Ozren Bauer has a revenge hit list, but is he lined up in someone else's sights? Olga persuades the former head of her humanitarian organisation to give evidence against the Kyiv Police Chief, Pavel.

The investigation reaches its horrifying conclusion. Olga, Vladimir, Vesna and Stribor's lives will never be the same again.

Stribor panics and goes to Belgrade to stop the publication of the video. Thanks to Khrinyev, Pavel is arrested in Kyiv.

The Osijek Avenger heads toward the final showdown. Can he be stopped? And at what price?
