There is a state of emergency shortly before the Kiel Week. Three million guests from all over the world are expected to celebrate the largest summer festival in Northern Europe. Now, of all times, a treacherously murdered woman is found in an empty apartment in the middle of the city center. There is no trace of the perpetrator, who had evidently set himself up in hiding for months. When inspector Borowski looks around the victim's apartment, he suddenly finds himself in front of a wall of fire. Roman Eggers and the inspector face each other for a moment. Eggers tries desperately to annihilate the consequences of his crime - and saves Borowski at the last moment. Then he disappears into the anonymity of the city, which is slowly filling up with people. When another body is found, Borowski and Brandt are alarmed: Are they dealing with a serial killer?
