Esther is suspected of terrorism because she investigated on her own initiative. In the prison cell she receives an offer from the military: Esther should develop a vaccine. When the courageous biologist refuses and demands the truth, she and her family are put under pressure. Ingvild Kampfjord, the prime minister's mastermind, blames party secretary Sandberg. Charlie, in solitary confinement because of his infection, could also thwart their plans and is therefore a political risk factor that should be eliminated!

Time is running against Prime Minister Heyerdahl. People are dying, the situation is getting out of control and the bacteria is spreading unstoppably, and there is no progress with the vaccine. Heyerdahl has no other choice: Norway has to ask for outside help. The World Health Organization fears a global pandemic and Norway is now trapped behind its own wall. Esther does everything she can to find Charlie. Only with his help can the biologist defeat the bacterium - and save her now infected son Johannes.
