A suspicious exchange brings the Antwerp State Security team on the trail of Bruno Lanssens. To whom does the ambitious man sell sensitive information? To find out more, Alexander makes a bold decision.

The team is convinced that it is only a matter of time before Gert Borlée takes action. The only question is who or what will be the target of this lone wolf? When his guns end up in a high school, every second suddenly counts.

Alexander feels guilty for what happened to Farah, but there is no time to think because a State Security van with documents disappears without a trace. The investigation leads the team to an animal rights organization.

While the team continues to search for Martine Vanhee's murderer, Rob secretly starts working on Inès' file on the murder of their daughter. He finds a trail that leads to Vic.
