With his next crime, the perpetrator wants to draw attention to the grievances of homeless people. For this purpose he distributes bottles of poisoned wine to homeless people. One of the victims is Sonja Lindberg, who is seriously injured and taken to hospital. Another victim is the homeless Bjørn Rasmussen, who is tied to a chair in a cellar and displayed live on the Internet. After a failed escape attempt, Björn is again tied to a chair, now with a cannula on his upper body, through which blood slowly drains from his body. Online viewers can watch him die because of the blood loss. Meanwhile, the perpetrator demands five million crowns each from four wealthy real estate owners to keep Bjørn alive. Meanwhile, the police are unable to trace the transmission of the truth terrorist, as the bridge murderer is now called in the media. Saga can, however, interpret Bjørn's blinking as Morse code, which is the serial number of an electricity meter in a disused factory building in Malmö. In their search for Bjørn, Martin and Saga are hindered by a masked man, who is probably the perpetrator and is able to escape despite the arrival of special units. For the weakened Bjørn, any help comes too late.

A few days later, the psychologically unstable Lasse Jönsson kills his psychologist in his practice with a samurai sword. His subsequent attempt to take his own life is prevented by employees of the practice. The Bridge Murderer contacts Ferbé again and draws his attention to the problem of extreme cuts in psychiatric care. Meanwhile, more strange murders occur in Malmö and Copenhagen, and it soon becomes clear that the Bridge Killer has incited psychologically unstable people to the murders with subsequent suicide. In order to find the Bridge Murderer, Martin and Saga interrogate the murderer Lasse, who is the only survivor of the four murderers and remains stubbornly silent.

In Lasse's apartment, the two detectives discover traces of Anja Björk, a girl who has run away from home and is temporarily living with him. Recordings from a surveillance camera in front of Lasse's house show Anja in a chance encounter with a man who comes out of the house and who could be the bridge murderer. Before the police can pick Anja up, Anja is hit by a bullet of the bridge killer. Shortly before she succumbs to her severe injury in hospital, she helps to create a half-finished drawing of the perpetrator's face. Martin sees similarities in the drawing with the face of Anja's brother Stefan Lindberg. During a search of his apartment, blood spatter is discovered and Lindberg is arrested. He affirms his innocence, the blood in his apartment does not come from any of the victims of the bridge killer, so that he is released. On the Internet, the Bridge Murderer draws attention to a fourth problem, the lack of integration of foreigners, by kidnapping and killing a police officer. The police officer had previously covered up for colleagues who had mistreated an immigrant to death by giving false testimony in court.
