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.

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.

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.
