Commissioner Jochen Maiwald must realize that he is not just an investigating officer but is more deeply entangled in the whole affair than he would like. The investigation becomes a race against time, as the murderer has not yet fully executed his sinister plan, and Maiwald also finds himself in his crosshairs.
