Unit 13 is put on a grant fraud matter, after it is threatened to be disbanded. They track it down to a pharmaceutical company called MediGEN. Karin Prinsen finds secret plans which have serious impact for the Dutch infrastructure at her stepfather's, which she can handover right before she's killed.

Inspector Harry seems to have had an accident. Sterk confiscates a videotape of Rieding on which top civil servants make agreements with a criminal organization. Roberto goes undercover at MediGEN and journalist Remco Haas house has been burgled, the information of Karin Prinsen he got is missing.

Doubts rise around the death of inspector Harry and the Unit intercepts a mysterious cargo on Zestienhoven, which proves to be legal. This is reason enough for Sterk to disband the Unit. Meanwhile the relation between Rieding and IMF-employee Rutger de Klerk seems to be getting more serious.

Bilderdijk takes control of the Unit during the absence of Sterk and tries to save the Unit. Alexandra goes undercover in private clinic Vita Nova after a patient has been found dead in the woods. Rebecca examines the practices of the new alderman of public scheduling and environment of the Haarlemmermeer, the banker Jeremy Cornwall has died under suspecious circumstances and a colleague of Govers seems have information on the death of Harry.

Sterk disciplines Bilderdijk, because he went behind her back. Journalist Remco Haas tells Ruard that the death of an alderman in the haarlemmermeer was a set-up. Toine is arrested on suspicion of the assassination on Harry and Alexandra discovers that Vita Nova is a coverup for an organisation which carries out illegal donor transplantations on African adopted children. The police arrest Irina Breitner. Spalding feels threatened.

The Unit has proved its legitimacy and is not disbanded. In the meantime they try find out who's the big man behind Vita nova, among other things by means of questioning Breitner and the observation of Secu Watch, where Ben Govers is in service of the Unit as informer. Meanwhile the investigation around the situation of the infrastructure plans in the haarlemmermeer is closely watched. The activities of Secu Watch appear not as pure and Ben Govers as informer is discovered.
