A boisterous bachelorette party takes a shocking turn when one of the partying women at the campsite stumbles over the site's owner's lifeless body. When the detectives arrive at the scene of the crime, they find the distraught Alex Reinhardt loudly discussing with the young Kira Demir. It quickly becomes clear that the perpetrator is still on the square. A race against time begins. Does Reinhardt have anything to do with the death of the groundskeeper? Or the Zeislers? Annette and Bruno Zeisler seem to be well informed about all the events on the site and accuse the self-proclaimed campsite sheriff Uwe Keupert. The detectives continue to grope in the dark and find no clue. Suddenly, Kira, who was escorted to school by the police in the morning, disappears.
