On a hot summer day, Erwin drives his tanker truck north across the Öresund Bridge whilst smuggling eight Syrian refugees. When he sees a police checkpoint ahead of him on the road, a fatal mistake leaves him with a life-changing choice.

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 Rainer receive the news that a Middle Eastern woman is injured in hospital. The desperate Rainer tries to find a way to deal with the new situation. Ahmed, who works at Erwin's father's retirement home, becomes increasingly concerned.

Erwin and Lunt find it increasingly difficult to keep up appearances. The police get an important lead. Anja 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 begins 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.
