As long as you breathe

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.
