After catching her boss and partner with another woman red-handed, the good-natured paralegal Katharina finally bursts the collar. She quits, quits her job and starts with her 16-year-old daughter Nele from Berlin towards the coast. On a small North Sea island where her mother runs a guesthouse, she wants to clear her head again. She had to promise Nele that she would finally only think about herself. Because Katharina is far too good for this world: As soon as she sees someone in need, she simply can't help but jump to his side. Unfortunately, because of this, she ...

The world still seems all right on the North Sea island of Föhr. The idyllic atmosphere also affects the attitude towards life of Katharina Reiff, who "fled" from the big city to the island. In the holiday pension of her resolute mother Marianne, she concentrates entirely on her distance learning law course and, to the delight of her daughter Nele, is determined to get her helper syndrome under control: people should kindly solve their problems themselves.
