After the murder of the Prime Minister's chauffeur, the Finnish Security Intelligence and the National Bureau of Investigation has set up a joint investigation team.
Finland gets a new Prime Minister and Ratamo's theory is confirmed. The team's primary goal is to find out who murdered Prime Minister Koskela and why. An important link is found.
The political climate between Russia and Finland becomes even more strained when the victims of a fateful assassination in Helsinki turn out to be Russians.
The Russian army has launched a military drill near the Finnish border. The SIS and the NBI have found solid evidence about Akulov's guilt, but the man is missing.
Ratamo and Linden are fighting against time to stop Akulov from carrying out his disastrous plan. But it is already too late - can anything stop the Russian military forces anymore?
