When the County Administrative Board discovers human remains in a dead wolf, the Haparanda police are contacted, and an investigation begins.

The police investigation leads Hannah and Gordon to Finland, while Kat arrives in Haparanda.

Kenneth confides in UV, who sees his own opportunities with the stolen goods; Kat sets her sights on Greger, Haparanda's drug lord; the blue car floats to the surface; Hannah finds out about Thomas' secret and tracks him down.

Roles are reversed when Greger has captured Kat and demands information about the drugs.

Sandra and Kenneth resort to drastic measures to save themselves, while Hannah and Gordon receive an unexpected tip.

Hannah and Kat finally come face to face.
