Further on a bomb explodes at the place where the unit is located and Lotti Werner doesn't survive the bomb attack.

The investigation into the bomb attack is being done by the state police. Ruard and Adrienne want to quit with the investigation of Scylla. A container with raw materials for plutonium is found. The girl who stole the briefcase is seen, but later on found murdered in the forest.

Talsma announces he will not be a part of the unit anymore and appoints Ben as his continuator. Harry investigates inside a whorehouse and is being beaten down.

A friend of the murdered girl helps the unit to find out who is behind the bomb attack. The convicted from the Scylla case is freed during transport and kills cleared Ruysdaal. De undercover agent Michael Zoethout is being caught while calling with his mobile and he's being locked up.

After the unfortunate ending of Zoethout's undercover job, Bilderdijk want an explanation from Talsma. There are only two links who can offer the unit some valuable information: Van Dalen and the ambulance personnel.

Talsma leaves for Brussels, it will be a valuable trip. Meanwhile Adrienne is not letting time pass by and that's not a happy thought for everyone. Bresler feels betrayed, reason enough for the unit to take action.

Swart takes revenge, after he just managed to escape death.Talsma tries to go in depth with his contact Lisa.

Bresler goes completely mad when he hears about the death of Shanti and this gives him some strange ideas. Together with the navy the unit prepares an ADI.

Ben is not happy about the visit of Vitti. Rauard, Ben and Adrienne on board of the navy ship are part of an attempt to arrest the suspicious ship Challenger.

The navy arrest is evaluated by the Public Prosecution Service. Aarts gets uncomfortable when the name Jeremy Cornwall is mentioned. Van Dalen is pressured during his interrogation.

Talsma wants to discredit the lawyer Vitti by all means. The state police gets the assignment to investigate the clumsy action of Kinky and Lobith. When Adrienne doesn't arrive at the meeting with Talsma, the unit is alarmed.

The tension is running high at the unit, when the role of Phoenix is becoming clearer. Adrienne is still imprisoned in the bunker and Lisa has very important information for Talsma. Kinky is interrogated about the action with Van Dalen. De politics are under pressure when the puzzle is almost completed.

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.

The Unit gets a few days to close the investigation of the office Leenmans & Venhuis. Bilderdijk informs rieding he doesn't want to stop the investigation of MediGEN. At a last attempt to stop MediGEN Rieding and Bilderdijk attend a shareholders' meeting. When it leads to nothing, Rieding decides to take up the proposal of Rutger de Klerk and quits as a public prosecutor.

Rieding says farewell to the Unit and leaves with Rutger de Klerk to the US. Govers also takes his dismissal and accepts a job at security company Secu Watch with which he came in contact during his investigation into the death of Harry. Kinky discovers the link between Leenmans & Venhuis and MediGEN. Roberto shadows Jolande de Wit who pays a visit to an adoption office and kidnaps her. Just when Roberto gets her to talk, they are fired at.

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.

Koops writes a letter as Breitner with evidence to Bilderdijk and Govers escapes an attack. Breitner has confessed partially, but is now demanding things and the Unit tries trace Toine, who survived a fusillade. The mysterious informant proves to be Mrs Prinsen and without knowledge of her husband, Rebecca and Kinky can obtain important information from the computer of her daughter Karin. Rutger de Klerk wants help the Unit from the IMF. In the meantime Josien sees her relation with Kinky going down the drain due to Alexandra, which has still processing problems as a result of her experiences at Vita nova.

Adrienne Rieding returns from the US, among other things because she wants to experience the resolution of the matter. Van Dalen wants to testify, but by is brought to Koops by bribed keepers, whereupon he assassinates him. The infrastructure plans which the Unit has got hold of by means of the computer of Karin, indicate a criminal network that has already infiltrated the Dutch polics and economy. It does not appear to be possible to find the big man behind the whole organization, because Prinsen, the last hope of the Unit, is assassinated aswell. Eventually the complete story will be printed in a newspaper Article, which was the only wish of Karin.
