Marlies Schrey, the wife of the knitwear manufacturer Gerd Schrey, is killed in broad daylight in front of a popular tourist restaurant. For detectives Dorn and Lessing, everything points to a failed kidnapping. The kidnappers report promptly: They also have Gerd in their power. They demanded a ransom of two million euros from his son Maik. The Schrey couple had taken out a kidnapping policy that expires in a few days. Did Gerd Schrey stage his own kidnapping to save his ailing knitwear company? Maik, who is courting his father's favor, is also targeted by the investigators: Marlies was his hated stepmother. Has the supposedly estranged father-son duo hatched a diabolical plan?
