A youth center burns down. The body of 40-year-old Ulf Meinert is found in the building. At first everything indicates that he started the fire, but then the chief inspectors Eva Saalfeld and Andreas Keppler find a lead that leads to Ludwig Kleeberg and his daughter Nadja. They own the land where the youth center was located. The Kleebergs want to sell it because their auction house is heavily in debt. So far, the project has failed due to resistance from the youth center operators. Did the Kleebergs order the arson tosurvive financially? Norbert Zirner, the owner of the boxing school, quickly fell into the inspectors' crosshairs. Just like Ludwig Kleeberg, Zirner was involved in the fateful events surrounding the demolition of the Paulinerkirche in Leipzig in 1968.
The commissioners get this important clue from today's art historian Hannah Wessel, whose son died in the fire at the youth center. Back then there were winners and losers. Are there old scores that need to be settled? Is this the key to solving the case?
