A passerby is pushed in front of a moving truck at the Kiel Fjord: an outbreak of violence from nowhere. Commissioner Borowski is listening to a nearby vocational school. A little later, the main commissioner lands in the intensive care unit with a serious head injury. Mila Sahin is of the greatest concern. Why wasn't she with him when her colleague needed her? She suspects a connection between the senseless act and the attack on Borowski. And then there are these strange calls that reach the main commissioner on the bedside: a girl named Finja claims to have been kidnapped by his sister Celina. Celina Lübbert is one of the girls Borowski interrogated at the vocational school.
