The young couple Hanne and Johan are traveling with a group of friends to a remote, mountain facility to investigate whether it can be refurbished and reopened. During their first night Hanne hears strange sounds coming from the basement. When the mysterious caretaker refuses to let them examine the sounds, the group grows suspicious.

Hanne continues, to Johan’s irritation, to explore the hotel's horrific past and suspects that there may be an evil supernatural force at the facility.

Hanne finds a new drawing depicting a death in the lake, together with the recurring message 'GAADEK JAAMIT' and looks for a local Sami person who can translate it. Meanwhile, tensions rise at the remote Swedish ski resort as friends don't know who to trust - everyone seems to be hiding something, and they are not making themselves popular with the locals. Jessan is recovering, and hatches a plan to find out what is going on, but it's not to everyone's liking.

Hanne becomes further convinced that something supernatural and evil threatens their lives. The suspicion is strengthened when she finds an abandoned, secret room in the basement.

Hanne is brutally attacked in the basement, but manages to escape. She leaves with Mette and Frank only for them to discover that Oswald has mysteriously disappeared and Lippi believes him to be locked in the basement.

Hanne finds evidence of the plant's history is darker than she first imagined. Meanwhile, Elin has got an eye inflammation that Hanne believes is a sign of the curse that haunts the building.
