In the countryside, she meets local officer Tom Petersen, Karla's brother. In spite of Dorn's warnings not to get mixed up in the case, he relentlessly searches for his sister's killer, suspecting friends and acquaintances alike.

The lost child.

Helen Dorn has never been able to forget the case of a boy who disappeared 14 years ago. She had been forced to release suspect Ron Faber at the time, and the missing child was never seen again. When Helen learns from an Intrapol report that Faber was picked up in Hamburg after an accident with the dead body of a Chinese boy in the back of his van, she immediately sets off for the city.

Helen Dorn and her colleague, forensic scientist Weyer, are enjoying themselves at Hamburg DOM festival when a young paramedic is assaulted and seriously injured in a nearby parking lot. Shocked by the brutality of the crime, Helen is determined to find the perpetrator. The next day, a boy from Hamburg's high society is found dead. During their investigation, Helen and her fellow officers come across a dark secret that ties the two cases together.

After a fellow officer shoots himself right in front of her while on a call, Helen Dorn faces her own feelings of guilt along with the unspoken accusations of her fellow officers, starting with Detective Chief Inspector Tayfun Murat. At the same time, she has to solve the murder of a young medical student. The detective's investigations take her to the oncology department at a hospital in Hamburg, and she soon finds out the victim had been leading a double life.

Chief Commissioner Helen Dorn has to deal with an arson attack. On a boat a fire was set and the owner, real estate agent Ralph Wagner, was killed. In the case of the autopsy, however, it is clear that Wagner was killed on a broken neck. Dorn learns from Wagner's company partner Thomas Lehmann that he and Wagner have been threatened by the left-wing extremists because they bought the building "Red Cloth" in which the left-wing center is located. The spokesman Dirk Müller denies any fault of himself and his group. Dorn learns that Wagner had a secret mistress Jasmin Friedrichs. That night she was with Wagner on the boat. The masked killer set the fire, killed Wagner, but saved her. She recognized Lehmann to be the killer due to his perfume, but does not mention this until now because she hoped to extort money from him. The motive was a discord between Lehmann and Wagner when, contrary to their former agreement of "sharing everything", Wagner wanted to have his beloved Friedrichs only for himself.

While hunting, Rolf Kanther, the director of a midsized manufacturer of military technology, is shot from a great distance in his raised blind, right next to his daughter Sonja. The circumstances are initially unclear - was it an unthinkable fluke accident, or a meticulously executed murder? Inspector Helen Dorn of the State Office of Criminal Investigations is assigned to the investigation. At the crime scene, she talks to Sonja, who is still in shock.

Bei einem Amoklauf an einer Stadtteilschule in Wilhelmsbug stirbt der Amokläufer Rocco Burhan unter mysteriösen Umständen. Helen Dorn sucht nach dem Täter und den Hintergründen. Sie dringt tief ein in die unübersichtliche und aufgeheizte Stimmung auf der südlichen Elbseite. Skepsis gegenüber der Polizei, Wut auf die Lebensumstände und fatale persönliche Verstrickungen der Beteiligten machen es Helen fast unmöglich, weiterzukommen. Erst als Helen sich in ihre vermeintliche Niederlage fügt, erkennt sie, worum es bei dem Fall wirklich geht, und was für alle Beteiligten auf dem Spiel steht.

During a video conference in Hamburg, Lydia Orlova and her mother Svetlana watch a murder taking place in an apartment in Athens via their computer screen.

Toni fährt mit seinem Alfa Romeo an einer Tankstelle am Stadtrand vor. Seine Tochter Luisa tankt und er spricht mit der Kassiererin, als zwei maskierte Männer die Tankstelle betreten. Die Männer eröffnen das Feuer. Der Toni reagiert mit traumwandlerischer Sicherheit und ersticht einen der Angreifer, seine Tochter Luisa eilt ihm zu Hilfe und erschießt den zweiten Angreifer. Helen übernimmt den Fall und muss den Mann und seine Tochter laufen lassen. Die Notwehr ist ihnen eindeutig nachzuweisen. Als man anhand von Fingerabdrücken auf Toni Vizzante vor fast 60 Jahren nach einem Brand in der Umgebung spurlos verschwunden ist, nimmt der Fall eine neue Wendung. Es stellt sich heraus, dass Toni kein Italiener ist, wie er behauptete, sondern im Alten Land lebte, bevor er bei einem Brand seine Eltern verlor. Je mehr Helen in dem Fall recherchiert, desto beunruhigender wird es für sie, denn der "Sizilianer" scheint auf irgendeine Weise mit ihrem Vater in Verbindung zu stehen, auch wenn der das vehement abstreitet.
