The prominent TV presenter Sandra Berger is dead. Gardening entrepreneur Britta Hausmann finds the TV lady beaten to death in her Usedom vacation home. Chief Inspector Ellen Norgaard is shocked when she meets the dead woman's husband, the equally well-known TV presenter Jonas Gomez, at the crime scene. The two are connected by the well-kept secret of a passionate affair. Karin Lossow senses that Ellen is in a bad way. The detective pours her heart out to her friend. Nobody at the police station suspects that Ellen was seeing Jonas Gomez at the time of the crime. It would mean the certain end of her career in the police force and the probable end of the career of her lover, who has no alibi for the time of the crime and is also being blackmailed.

School secretary Annett Ludwig is jogging by the sea. She discovers a dead teenager under a steep cliff: Theo Jacobsen, a pupil at her school. The 17-year-old was considered an inconspicuous outsider. Karin Lossow knew Theo from commercial school, where she led a course on legal issues as part of a project week. By chance, she had witnessed a bullying attack on Theo, who was at the top of his class, and offered to help the boy. Rainer Witt and his colleagues Holm Brendel and Dorit Martens investigate Theo's laptop. It turns out that he was engaged in a lively trade in test questions, which he sold to his classmates and made thousands of euros in profit. To do this, the alleged model pupil used access to the headmaster's surfer - only school secretary Ludwig knew the password.

The next day, Karin sees Dana's husband Jochen driving off the ferry in his SUV - without his wife.

North Friesland today: After the death of his father-in-law, Hauke Haien takes on two important roles in coastal protection - dyke count and director of coastal protection. Professionally, Hauke is the best man for the job; he is a visionary who lives and thinks in harmony with nature. Only people are not his cup of tea. As a loner, Hauke hardly knows how to inspire an audience and win over fellow campaigners. His warnings about the effects of climate change are dismissed as hysteria in the village, even though the coastal inhabitants know that a drastic change of course in climate policy is unavoidable. Fortunately for Hauke, his wife Elke supports him. She manages to make him heard. But Hauke does not enjoy his success for long, because when it becomes known that his plans are much more radical, he is met with incomprehension and anger. Resistance and pressure wear on him. Disaster can no longer be averted.
