African-American physicist Andrew Routledge takes a plane flight in a blizzard to attend a world-class conference on quantum mechanics. Fate has other plans when his plane crashes in a nightmarish world where the snow never stops and a menacing evil curse, buried deep within the darkest chapters of American history, rises again. Andrew's only hope to escape is a strange whistle that he must figure out how to use before the snow stops forever and the apocalyptic Shadow Man appears on the horizon...signaling the doom of all.
