Bremen Harbor. A man's body is found in the harbor.

At first glance, the Bremen inspectors Moormann and Selb are dealing with the suicide of a mentally ill person. After a house fire, the tenant's body is found in her hermetically sealed bedroom. [Harbor Crimes.]

In Bremerhaven, one of the largest automobile transshipment ports in Europe, a body is found at one of the car terminals - the driver area manager is lying dead in the trunk of a car.

The Bremen investigative team with Liv Moormann and Linda Selb begins the investigation and is supported by their Bremerhaven colleague Robert Petersen.

They come across Marie, Gheorghe Rusu and Oleg Rusu. The three car tuners secretly send cars along for night races and compete in spinning "doughnuts" when the car slides in circles with smoking tires. One of the vehicles turns out to be particularly explosive.

Liv Moormann quickly finds herself in the middle of the car tuning scene - and as a native of Bremerhaven, she not only meets forgotten friends, but is also confronted with her own family.

A micro-adventure turns into horror: The friends Ayla Ömer, Viola Klemm and Marlene Seifert try to find their way back home from the deep forest without any technical aids. They want to test whether this "dropping" in unfamiliar terrain is safe for their sheltered teenage children. But when night falls, the three neighbors from middle-class Bremen-Schwachhausen are lost in the forest - and the next morning one of them is dead.

The Bremen investigators Liv Moormann and Linda Selb encounter many inconsistencies and numerous suspects. On the one hand, there is the “cell phone man”, who years ago secretly photographed campers while they were sleeping and is suspected of murdering a woman. On the other hand, the seemingly intact facade of the well-off neighborhood with the husbands Klaus Seifert, Emre Ömer and Mirko Klemm gradually begins to crack. There are also arguments among the teenage children. Selb's aunt, Johanna Selb, has a lot of insider information about the suspects.

Captain Hendrik Wilkens lies shot dead in his room on Christmas Day. He and his husband had taken in a Filipino sailor for the holidays. Together with Hendrik's children and grandchildren, it was supposed to be a peaceful Christmas. For Liv Moormann and Linda Selb, it looks like a robbery and murder. But was life really as harmonious in the Wilkens family as it seems?

When a body washes up on a beach on the Weser River, Bremen investigators Linda Selb and Liv Moormann are faced with a mystery. Initially, there are no clues as to the body's identity. In the course of their investigation, the detectives not only encounter stalking perpetrators and victims, but also explosive investigative research and toxic addictions. Meanwhile, Rani Ewers is living a nightmare: Her ex-boyfriend Marek Kolschak is lurking everywhere for the single mother and her daughter Mia – at the playground, on the street, in front of the front door. When she finds the framed family photos on her wall defaced after a visit to the playground, her roommate Paula Södersen urges her to finally report him. Forensic pathologist Edda Bingley provides the team with crucial clues. As clear-cut as the case initially appears, the lines become increasingly blurred, witnesses become suspects, and suspects become witnesses, who suddenly find themselves in mortal danger.
