Valkyrien S01E01 - Undergrunnen

Deep underground, below Valkyrien Square in Oslo, doomsday prepper Leif Lien has arranged for doctor Ravn Eikanger to carry out his research in secret. While Ravn is up on the surface burying his wife Vilma, one of Leif's many alarms goes off. A robbery has gone terribly wrong, and the severely injured robber Teo seeks refuge with Leif. Without medical attention, Teo will die. And Ravn owes Leif a favour.
