The six-part series follows a journalist, Hannis Martinsson (Ulrich Thomsen), who unexpectedly receives a message from Sonja, a daughter he did not know of, claiming that her life is in danger. He arrives in time to help search for her and discover her body. Initially the authorities assume accidental drowning, despite anomalies in the known facts. Hannis suspects her death may have something to do with her anti-whaling activism and that a local businessman, Ragnar, is somehow involved. Although the police officer investigating Sonja's death, Karla Mohr, is also suspicious of Ragnar, she conceals evidence that might lead suspicion to fall on her own son.[3]
