As Paleoclimatologist named Jack Hall is in Antartica, he discovers that a huge ice sheet has sheared off. But what he does not know is that this event will trigger a massive climate shift that will affect the world population. Meanwhile, his son Sam is with friends in New York to attend an event. There they discover that it has been raining non-stop for the past 3 weeks, and after a series of weather-related disasters begin to occur over the world, everybody realizes the world is entering a new Ice Age and the world population begins trying to evacuate to the warmer climates of the south. Jack makes a daring attempt to rescue his son and his friends who are stuck in New York and who have managed to survive not only a massive wave but also freezing cold temperatures that could possibly kill them.

INTER SCI climatologist David Koch has evidence that a shift in the Earth's polarity triggered the last Ice Age...in a single day. Now, it's happening again, and there's no time to escape. As the temperature plummets, Miami is blasted with snow and ice. Evacuation routes are jammed. The only chance David, his old flame Bryn, and a few other hopeful survivors have is to hole themselves up in a special chamber at INTER SCI. A desperate race for survival is ignited as nature's fury rages and the temperature plunges toward -459.67° F...ABSOLUTE ZERO!
