[2] Nikolai Andreassen, a police detective from Oslo, is visiting his home town, near Tista river and Swedish border.

He is drawn into the investigation of the suicide of a local man named Tommy Hagen; his co-investigator, Anniken Høygaard-Larsen, from the National Criminal Investigation Service, suspects foul play.

Nikolai plants evidence in order to protect his younger brother, Lars, who appears to be implicated, but later discovers the truth behind Hagen's death.

[3] Meghan O'Keefe of Decider called the series "as dark and atmospheric as Scandi-noir comes, but it’s also elegantly beautiful and extremely tense".
