Potsdam's best-known restaurant critic, Valentina Scholz, is found strangled in her car. Suicide can be ruled out quickly. Valentina had hardly left a good word at any restaurant and had written some scathing reviews. Thus, almost all of Potsdam's top gastronomy has a murder motive. Not an easy task for the investigators of the SOKO Potsdam. The first clue is Saul Schlegel. The restaurateur is on the ground after Valentina's scathing, the restaurant is empty. On the recordings of the surveillance camera, an argument between Valentina and him can be seen.
