Arctic Circle

Nina Kautsalo is police officer and a single mother in her hometown of Ivalo in Finnish Lapland; with her partner she finds an unconscious woman held captive in a farm cellar.

The police must work hand in hand with the health department to combat the virus that has been claiming lives at an alarming rate; another threat approaches.

After threatening Nina, Raunola went to the police, pretending to be afraid of an external threat; his test for the Yemeni virus is negative; only Marita and Evgenya carry the virus.

The government units are not the only ones curious about the virus; the doctor's wife does something unanticipated; a prostitute takes a risky step.

Nina persuades Raunola to talk by offering him the chance to get a mental health assessment; Thomas returns to Ivalo, where they have started testing pregnant women.

Irina reveals to Nina the behavior of oligarchs in Murmansk and explains how the young girls were secretly taken to Finland; the young woman looks terrified at the mention of Cevikovic.
