In
Jotunheimen, a boy with a large
birthmark covering the left eye runs frantically through a blizzard, pursued by an unknown entity. Eventually, his pursuer catches up to him and bury him alive in the snow. Years later, a young group of friends consisting of Jannicke, her boyfriend Eirik, and their friends, Mikal, Ingunn, and Morten Tobias are going on a snowboarding vacation in Jotunheimen. Morten Tobias took a bad fall from skiing and broke his leg. Jannicke sets his leg but they have no cell reception and their car is too far away for medical evacuation. Wandering over a hill, they spot a lodge and decide to seek help there. Eirik discovers that the lodge is deserted, broke in and unlocks the door. As Jannicke looks for medical supplies she comes across a box that contains superglue and a single shotgun shell. Jannicke attempted first aid on Morten's broken leg with alcohol and the superglue. Eirik, Mikal and Ingunn explores the abandoned lodge, and discover a
generator, which Eirik fixes and restores power to the lodge. With the lights back on, music playing and plentiful amounts of food and alcohol, the group relaxes in the parlor. Jannicke finds the hotel's guestbook and discovers that the last guest checked in some time in 1975 and there is a message reading "We hope you find your son". Inside the book, there is a picture of a family that includes the boy with a birthmark over his eye. The group settles in for the night with Mikal and Ingunn running off to a suite, Jannicke and Eirik cuddling under blankets in the parlor, and Morten Tobias alone on the couch. Making out in bed, Ingunn rejected Mikal advances and Mikal leaves to compose himself by the bar. Alone, Ingunn enters the hallway after hearing strange noise and is ambushed by a man wielding a
Pickaxe. Her scream for help is drowned out by the music playing and she is stabbed by a pickaxe and dragged away. The next morning, Eirik leaves the lodge to look for help while Mikal heads to the suite to apologize to Ingunn. Eirik stumbles upon Ingunn's dead body in the snow and was knockout by someone. As Mikal receives no replies from Ingunn, he and Jannicke explores the basement and found old but important items not usually left behind by travellers. Jannicke goes to talk to Ingunn only to discover the suite covered in blood. She brings Mikal and Morten Tobias to the bloodied suite and they realize someone else is in the lodge. They barricade themselves in an empty suite and footsteps are heard in the hall and someone begins to slam against the door, trying to get in. Mikal scouted the lodge after it quiets down and discovers a Massive Mountain Man too tough to deal with before returning to Jannicke. Mikal tells Jannicke they should run leaving Morten Tobias but Jannicke refused. Mikal escapes through the window alone but was caught by a
Bear-trap by the shed. Unable to run, he hid in the shed when the Mountain Man approaches. Jannicke and Morten Tobias watch through the window as Mikal fought and loses against the Mountain Man. Jannicke hid Morten Tobias to a pantry room while she scout for things they can use to escape the lodge. She narrowly misses being spotted by the Mountain Man as he drags Mikal's body inside. Jannicke runs to the shed where she finds some skis, a sled, and a
shotgun. She returns to Morten Tobias with a loaded shotgun and tells him she has a plan. Jannicke and Morten Tobias kills the generator, baiting the Mountain Man to the basement. Morten Tobias finds a
box cutter and puts it in his pocket and hid himself. Jannicke enters the back room and found Eirik tied up but alive. Unable to free him, she goes back into hiding near Morten Tobias. When the Mountain Man appears going into the back room, Jannicke points the gun at him, but he shuts off his flashlight and disappears into darkness. Thinking quickly, Jannicke shuts the door and locks him in the back room but refuses to leave him in there with Eirik. Opening the door, she shoots but is knocked askew by Morten Tobias who realizes the Mountain Man is using Erik as a human shield. The Mountain Man impales Eirik with his pickaxe, killing him. Morten Tobias tells Jannicke to run and tries to kill the Mountain Man but to no avail. Jannicke grabs her skis from the shed and runs outside into the darkness only to be knocked out by the Mountain Man. Jannicke wakes up buried under her friend on a sled. The Mountain Man is tossing her friends one by one into the deep
ravine. Jannicke grabs the box cutter out of Morten Tobias's pocket and feint death. Jannicke, the last to be dragged off the sled, stabs the Mountain Man in the neck with the box cutter. They struggle over the pickaxe near edge of the ravine. Jannicke manage to rip off the Mountain Man google revealing his birthmark over his eye. This surprises the Mountain Man and Jannicke grabs his pickaxe and stabs him in the stomach, sending him over the ravine. In a flashback, we see the Mountain Man as a boy, running from his pursuer. As he is covered in the snow, he looks up to see the faces of his parents burying him alive. The Mountain Man hits the bottom of the ravine, surrounded by the bodies of Jannicke's friends. Jannicke, exhausted, collapses into the snow. ==Cast==
