A cold wind sweeps across the planet, leaving death in its wake and threatening to put the entire human race into deep freeze in this breathtaking ecological thriiller from Australian director Brian Trenchard-Smith. It all started when a U.S. research vessel ran aground in Australia. Inside, a grim discovery: the entire crew of 15 has died from no discernable cause. Upon learning of his colleagues' inexplicable deaths, world-renowned physicist Jack Tate (Michael Shanks) vows to uncover the cause as the divorce with his wife Emma (Alexandra Davies), the town medical examiner, is finalized. Meanwhile, the strain in Jack and Emma's dissolving marriage has caused their teenage daughter Naomi (Indiana Evans) to become bitter and withdrawn. When the pieces of the puzzle start falling together and Jack realizes mankind may be witnessing the dawn of a new ice age, he presents his findings to the scientific community, which openly derides his radical theory. But they have no choice but to accept it once the frigid wind blows onto land, claiming countless more lives. Now, as the authorities race to evacuate the town, Jack calculates that it won't be long before the lethal wind sweeps across America as well. When the government fails to stop the storm, Jack devises one last plan to save the human race by working with Mother Nature, rather than against her.
