When Smilla's young neighbor, Isaiah, tragically dies after falling from the roof, the police quickly dismiss his death as an accident. However, Smilla believes otherwise.

Karsten Tork, an ambitious entrepreneur, and Katja Claussen, a right-wing politician, form an unlikely partnership.

Smilla is still unaware of both Tork's interest in her and Rahid's double game.

Unsure of where else to turn, Smilla pays a visit to her father, Moritz.

Sensing Smilla's plans, Moritz agrees at the last minute to accompany Tork, desperately hoping to protect his daughter.

As the expedition ventures further into the unknown of the icy plains of Greenland, Moritz desperately tries to protect Smilla.
