FBI Special Agent Karen St. Cloud and TV news anchor Peter Wilde are a part of an international search for 12 missing nuclear weapons that have disappeared somewhere in Antarctica in the control of a shadowy deep ecology group. The eco-radical group EPG* then threatens to destroy the West Antarctic ice sheet to start a new ice age and end civilization as we know it. US President Clark and senior officials are skeptical of the claims until EPG* detonates a warhead in Antarctica. The action takes place across three continents and the South Pacific. Compounding the confusion is a major Nor'easter that paralyzes the US East Coast, massive solar storms, alien First Contact, and mysterious voodoo Loa who appear intent on destroying humanity.
