Necrosis [2009, USA, horror, thriller, DVD5]

Michael "Mike" Scottfield invites his girlfriend Karen and his friends Matt, Jerry, Samantha and Megan to travel to Sierra, Nevada, to spend the weekend in his cottage in the top of the mountain. When they stop in a bar, the strange Seymour advises that the top of the mountain is not a safe place, and Mike explains to his friends that in 1846, a group of travelers was trapped for months in the mountain while traveling to California. They go insane with the starvation, and without any food, they start killing each other to eat. The episode was known as the Donner massacre. While driving a snowmobile, Jerry sees a ghost girl that advises him that the place is not safe. The six friends are surprised by the severe snow and are trapped in the cabin. When they go to the shed to start the generator, they find the body of the caretaker Lyle lying on the snow. Sooner Jerry sees other eerie creatures wandering around the cabin. When Matt learns that Jerry is under the medication of the antipsychotic Seraquin, they fear that Jerry may be driving crazy.
