A truck driver reports that he believes certain shipments he transports from the port contain cocaine. He reports to the detectives in order to catch the perpetrators in the act. But that is up to public prosecutor Berg to decide. He does not want to put a citizen in danger, but the man himself and the detectives insist. Berg eventually gives in, but is that a good idea? Stan begins to understand that there is more going on with his former partner Ben. And that the mysterious Van Nieuwerbroek has something to do with it. Officially, however, he cannot take any action against him.

Van Nieuwerbroek must be released on Hein Berg's orders. When he is found murdered the next day, Stan is the prime suspect. Hein and Lieve suspect that the mysterious Hunter Vaals played a role in the murder of their former colleague Ben. Hein instructs Esther and Dries to find out who Vaals is. This turns out to be a more dangerous task than they realize. Meanwhile, Stan manages to get out of the cell block after an interrogation by the national police. He knows he has to warn his colleagues. But he seems to be too late.
