A human trafficker and two police officers are killed in a gas explosion near a container terminal. In the vicinity of the terminal, a number of people were dependent on the dead smuggler: the forwarder Dreyer, the loadmaster Martinsen and the obscure security guard Jertz. Falke and Lorenz, who are investigating the human trafficking ring together with their colleague Jan Katz, are faced with a wall of silence. Falke and Lorenz also approach the desperate refugees who were picked up in a container and the traumatized colleagues of the dead police officers, above all Gerd Carstens, from a distance.
