The series also tells the story of Klaus Feller in parallel. In a financial emergency, he committed an insurance fraud in earlier times. Together with his then-wife Renate Feller, he faked his death and cashed in the life insurance policy taken out on him, which he consequently shared with Renate. Klaus Feller then went into hiding. Under the false name of Harald Kuhn, he now runs a car rental business and repair shop on Mallorca. The situation gets dicey when his ex-wife surprisingly shows up on the island together with her friend Jens Hartmann and Ewald Stronk, a former customer of Klaus Feller, who recognizes him by his voice. To save his own skin, Kuhn flees into the mountains to the caveman and hermit Manfred. Stronk takes up pursuit with one of Kuhn's cars, but crashes with it and has a fatal accident. The search for the culprit becomes a nerve-wracking game of patience....
