In a fast-paced chase, the Erfurt investigative duo, Chief Inspector Henry Funck and Chief Inspector Maik Schaffert, are able to arrest Roman Darschner, who is suspected of having murdered multiple women. However, one woman seems to have fallen victim to the murderer before he was caught: the beautiful student Anna Siebert, 24, was found dead on the Gera. Together with the inexperienced police intern Johanna Grewel, who was literally thrown under their noses by their boss, detective director Petra "Fritze" Fritzenberger, the inspectors set off to the scene of the crime. The first investigations indicate that Anna, like the other women, was tortured and killed.
But why didn't Darschner completely undress his victim this time? Should he have been disturbed? Darschner himself denies any involvement in any of the murders. The search of Anna's small student room paints an unusual picture of the dead: Anna Siebert not only had expensive clothes, she was also apparently preparing to move into a large, new rental apartment. Lisa Kranz and Valerie Bultmann, two acquaintances from Anna's environment, also describe the dead woman as a person who used others for his own purposes.
Where did a student get so much money from? A rich friend, a sugar daddy? Was Anna really the last woman to be killed by Roman Darschner? Or was she the victim of another violent crime? These are just some of the questions that lead the young inspectors and their intern deeper and deeper into today's student milieu during their investigations. In the end, an exciting jigsaw puzzle of injured love, drugs, violence emerges - and the question of whether another fragile life can be saved in time?
