Wisting

William Wisting, a widowed senior detective in the Norwegian coastal town of Larvik, leads a murder investigation in which a body is found in snow underneath a Christmas tree. The clothes on the corpse show that the person killed was an American. An FBI team is immediately flown to Larvik and an international hunt for a serial killer begins.

Meanwhile, William's daughter Line, a journalist, investigates the lonely death of an elderly neighbour for an article. When her twin brother Thomas returns to a usually sleepy Larvik to celebrate Christmas with the family, he finds both William and Line deeply preoccupied with their investigations.

With FBI agents Griffin and Bantham added to the team, the investigation is making progress, but Griffin cannot adjust to Larvik's sleepy ways and finds some of her new colleagues unprofessional.

Meanwhile, Line thinks there's something suspicious about the death she's writing about, but William is convinced she's getting ahead of herself.

Wisting's team continue to search the bottom of wells all over town for more gruesome clues. They realise that the killer could also have been operating across the border in Sweden, potentially multiplying the number of victims.

Line's investigation is also becoming more complex, meaning Thomas has his work cut out trying to unite the family at Christmas.

Maggie pursues some unpopular, and not very Norwegian, investigative methods. Meanwhile, a discovery is made in the Larvik countryside. It's the breakthrough the investigation needed but also the one they all feared.

Line continues interviewing Viggo's old schoolmates and meets some interesting local characters along the way.

With the help of the Americans and the Swedes, Wisting's team have found more and more victims, but now Line herself has been kidnapped and Wisting faces a race against time to rescue her from the man they have been tracking all along.

Wisting and his team are basking in the success of their recent case. But from out of the blue comes an accusation that they, and specifically he, tampered with evidence in a case 17 years ago.

William is fighting for his reputation and his career.

Internal Affairs investigate Wisting, and following his suspension, Torunn heads the investigation into the disappearance of a young woman. Line runs into an old flame while working on her Ravneberg story.

Wisting fights for his career and reputation, by conducting his own secret investigation into the Cecilia case. Torunn suspects Linnea is responsible for her own disappearance, but her parents are convinced she is in danger.

Suspended detective Wisting resorts to desperate measures to prove his innocence, while Internal Affairs puts his police department under intense scrutiny. Benjamin searches for suspects in Linnea's disappearance.

Wisting and former colleague Robekk join forces on the Cecilia murder case, but will they figure out who was behind the evidence tampering? When Line uncovers a mysterious videotape connected to her father's case, clues point to Linnea's abduction. Will they manage to save Linnea before she is killed?
