Series 1 (2016)

Johan takes his brother and six friends to the north of Sweden because he is thinking of purchasing a disused ski hotel close to the border with Norway. It never officially opened because a family of four was murdered in the hotel's cellar shortly before it was due to open twenty years earlier. Johan's girlfriend, Hanne, who suffers long-term guilt over the death of her younger brother, quickly comes to believe that the building is possessed by the spirit of a dead child (a myling). At the same time, the surly caretaker, Erkki, is trying to scare them away from the property, with assistance from two Norwegian brothers who run a nearby snowmobile business.^[7] Having accepted Johan's marriage proposal, Hanne becomes friendly with Jostein, the younger of the brothers.

Hanne has found a series of child's drawings and these seem to become reality during the stay. Sami words written on paper and walls around the hotel mean "kill or be killed". The group holds a seance where the ghost of a boy named Mikkel seems to be trying to contact them. Jessan, one of the women, gets a red eye, and starts to behave strangely. Hanne speaks to the detective who investigated the first murders. He tells her that he thinks Helgesen, the resort's previous owner, was not convinced he had done the killings despite confessing to the crime. When Jessan tries to kill her boyfriend, Frank, she is subdued and tied up. Hanne discovers from talking to her that Jessan has been having nightmares. Jessan then discovers her bindings have become loose and hides in the toilet. When the police break down the door, she is found dead with a frozen scream on her face.

Osvald, who is secretly dating Johan's brother, gets a red eye and disappears in the cellar. Hanne finds the cellar door open and goes in to investigate, but is attacked and has to flee from the unseen attacker. In the cellar, she finds a secret room that contains medical files, relating to an earlier period when the hotel was a sanatorium. Hanne, her sister Mette, and Frank decide to leave, but Hanne thinks she sees a child in the road, and grabs the steering wheel, causing the vehicle to crash. Lippi is injured in the cellar after finding Osvald's dead body there. Mette, who is a doctor, returns just in time to save Lippi. Meanwhile, Elin, an old flame of Johan's, has a red eye and starts to walk around in a trance. Under the influence of the "kill or be killed" words, she strangles Lippi. When Johan finds her bracelet and realises she has killed his brother, he strangles her to death.

Mette discovers that Erkki wants them gone because he has allowed Dag and Jostein to use part of the cellar for growing cannabis. Johan and Frank confront the brothers, but Dag stabs Johan and slits Frank's throat. When he attempts to kill Hanne, Jostein shoots Dag dead. Hanne walks into the mountains and communes with her dead brother, Jacob. During another seance, Hanne is attacked by something and gets a red eye. All three go to Erkki's house. He eventually admits that he and his half-brother Mikkel lived with their doctor father at the sanatorium. Erkki's mother was a Sami who had a relationship with his father. But because he believed in Aryan superiority he saw Erkki as belonging to an inferior race. After Erkki beat his brother in a fight, his angry father strangled Mikkel for being weak.

After returning to the hotel, Hanne notices that one of the child's drawings shows the bed in the cellar's secret room with a space underneath. Climbing under the floor, she recovers the body of Mikkel. Before they can give the body respectful funeral rites, Erkki stops them. Johan, who now has a red eye, has survived the stabbing; he returns and shoots Erkki. However, outside the cellar Hanne kills Johan when he attempts to kill Jostein. Hanne, Mette and Jostein burn Mikkel's body on a traditional funerary pyre. They then pack their things and leave. However, on the drive back to civilisation, Jostein removes his sunglasses to reveal he now has a red eye.
