Syrian refugee Mouna manages to escape Erwin and Rainer, who continue to search for her. At the same time, Erwin is tormented by what he has done. Police officer Anja Kovacs comes into contact with a driver who gave Mouna a lift.

Erwin and Lunt find it increasingly difficult to keep up appearances. The police get an important lead. Anna begins to question whether the baby in the hospital is Mouna’s. Erwin’s daughter Sonja and Anja’s son Adrian attend a party that ends badly.

When a woman disappears from a retirement home, it leads to a surprising opening in Anja’s investigation. At the same time, she is reminded of the death of her brother and father in Bosnia. Erwin, under pressure, is close to a breakdown.

The strings begin to tighten. The media follow the investigation closely. As Anja gets closer and closer to the truth, Erwin realises that he must tell the police everything. But Rainer is determined to stop Erwin.
