One spring morning, a grimy note from a boy calling for help is discovered on a footpath near Flensburg harbor. A few months earlier, Rosalie Wiesner had reported her 15-year-old son Dominik missing. After a brief investigation, Jana and her team had called off the search based on a goodbye note they found, concluding Dominik was not a victim of foul play, but had chosen to run away from home.
