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.

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.
