Necrosis (released internationally as Blood Snow) is a 2009 independent psychological thriller film directed by Jason Robert Stephens and stars James Kyson Lee, Tiffany, George Stults and Michael Berryman.

[1] During the winter of 1846, a group of ill-fated pioneers, known as the Donner Party, were on their way to California through a newly discovered mountain pass.

An epic snowstorm interrupts their vacation, trapping them on the mountain and resurrecting the haunting ghosts of the Donner Party.

They struggle to find out whether these are the true demonic 'entities' or if it is simply 'cabin fever' that is bringing out their fears and paranoia, causing friends to turn against each other as their reality deteriorates around them.
