It is 2020. Findings by environmental scientist Professor Thom Archer suggest that Halo, the corporate energy company drilling on the Greenland Glacier are causing it to melt. Archer's warnings are ignored, so he heads to the Arctic to find indisputable evidence. Upon arrival, he realizes humankind is under immediate threat, and races home to save his family. The glacier collapses, with devastating consequences. Astonishing weather patterns emerge and plunge the world's temperatures into steep decline.
