Season 1

When Smilla's young neighbor Isaiah tragically dies after falling from the roof, the police quickly dismiss his death as an accident. Determined to uncover the truth, Smilla embarks on her own investigation.

Karsten Tork, an ambitious entrepreneur, and Katja Claussen, a right-wing politician, form an unlikely partnership. Smilla grows closer to Rahid, who was responsible for taking Isaiah to his regular hospital visits.

Smilla is unaware of Tork's interest in her and Rahid's double game. Ravn realizes that Smilla might be right about her suspicions of Isaiah's murder while Isaiah continues to communicate with Smilla through visions.

When Smilla is accused of murder, Rahid helps her escape. She also pays a visit to her father, Moritz. To her great shock, she learns that Tork is with him, preparing for an expedition to Greenland.

On the open sea, the expedition sails towards Greenland. Smilla has managed to evade detection on board for several days and reunites with familiar faces.

The expedition ventures further into the unknown of the icy plains of Greenland, where hidden answers await.
