Jannicke, Morten Tobias, Eirik, Mikael and Ingunn are on a snowboarding vacation in Jotunheimen. They are forced to take shelter in an abandoned hotel when Morten Tobias breaks his leg and their car is too far away for them to reach within nightfall. They quickly discover that the hotel was closed in the seventies due to the disappearance of the managers' son. Unknown to them, someone is still living in the hotel, and getting home, or even surviving the stay, isn't as easy as they believe.
Estranged friends Leo (a crime-scene cleaner) and hired-hand Elvis are cleaning up a particularly messy casualty deep in the Norwegian woods. When Leo accidentally finds a secret passage that leads to a subterranean living space, he also encounters Thale, a beautiful young woman who sings, but does not speak. Though they are intrigued and concerned for her, they are ill-prepared when others, tracking Thale, finally catch up to her.
