Valkyrien

A patient in the underground clinic seems to suffer from a common influenza, but it turns out to be a highly contageous and deadly bleeding fever. With a potential pandemi in hand Leif panics and scrambles his brother and his fellow preppers, but Unn and Ravn works hard to try to contain the damage.

When Vilma finally wakes up, no one is there. She starts wandering about, leaving the tunnels, and entering the world outside. She is picked up by the police and brought to the hospital, where Ravn finds her, and brings her home. Per finds a way into the secret tunnels, where he confronts Teo and Leif with fatal consequences.

It is not easy to return to society, when you are officially declared dead and buried. So Vilma and Ravn has a lot of explaining to do. Both to Siv, Vilmas family, the police and to the public. Teo has turned himself over to the police and is now in jail. And Leif has a problem with the underground clinic, which is now without doctors. What to do with the patients?

After Leif sabotaged the power system in the city, chaos rules in Oslo. The citizens have no water, no gasoline, no heating and no communication. The hospital runs on emergency supplies, but after three days problems arise. Leif and Unn decides to take some of the patients to the underground clinic, which is still operational.
