The police have foiled a terrorist plot but they're left no closer to having solved the mystery of who killed Finnur, or why Gisli took the actions he did. Now his sister and victim, the Minister for Industry, is coming back home for his funeral. Half the town will also be in attendance, and Andri and Hinrika are on the lookout for any signs of family tension. Meanwhile Asgeir follows up on his suspicions about Finnur.

In the aftermath of another killing at the plant, Vikingur is found covered in blood, and with his fingerprints on the murder weapon. It is all Hjortur can do to keep the other workers from tearing him apart until the police arrive, and now he is in custody at the station for a murder he swears he did not commit.

The shock is felt by Vikingur's troubled family, and by Andri and Hinrika, who clearly must charge Vikingur. Ebo, alone and in danger without Vikingur to protect him, looks for sanctuary with Vikingur's friends. Meanwhile Asgeir has agreed to investigate the mystery of the dead animals Ketill has been finding up at the lake.
