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.

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.

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.

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.
