Valkyrien

Surgeon Ravn Eikanger becomes furious when his supervisors do not allow him to test experimental medical procedures on his dying wife. In desperation, Eikander fakes her death as an apparent suicide and brings her to a makeshift clinic in the abandoned subway station Valkyrie. He is aided by Leif Lien, a paranoid prepper, who allows Ravn stay hidden if he operates an underground hospital where those who do not trust the Norwegian health care services can seek help.
