In the small town of Pregau, 16-year-old Rosa Hartmann dies in a car accident. Her friend Gregor was in the passenger seat and has been in a coma since the accident. The policeman Hannes Bucher blames himself for the accident, since he had subjected the two to a traffic check. Now he's trying to cover up the clues.

Inspector Hannes Bucher is assigned to his own case. He lies and deceives a lot of people to keep the truth from getting out. Hannes' nephew Sebastian senses that things are not right. Sebastian wants to find out what exactly happened that night when Rosa died. He seeks out Max Dirrmeyer, a possible witness. The Hartmann brothers, meanwhile, try to win the deputy mayor Feichtiger on their side with a nasty intrigue and eliminate their toughest opponent Hölzl.
