A Finnish person is committed to hospital after a car accident. In hospital they find out he has radiation sickness due to an overdose emission and in his car a briefcase with plutonium is found. The court case against Scylla started aswell.

Bilderdijk is really angry because Swager, the advisor of the minister is supposed to have committed suicide. Harry is tracking down the witness called Lotti Werner. When the team appears at the meeting place of the Finnish person with the briefcase, the briefcase is taken. 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.

The box with the raw materials of the plutonium is emptied, is being bugged and shipped to Spain. Michael Zoethout travels with the ship undercover. The main witness of Scylla is set free. 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.

Talsma is going on investigating during his vacation. Harry meets an old friend, but she proves to be working for Phoenix. 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.

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.

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.

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.

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.

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.
