During World War II, at a secret Nazi submarine base, containers crafted entirely from looted wartime gold were hidden away. The treasure was not the solid-gold chests, but the cargo they carried - an artefact so lethal that whoever possessed 'Pandora's boxes' held the power to unleash hell upon the Earth . . . In the unforgiving wastes of Greenland, geologist Philip Mercer uncovers a long-abandoned U.S. Army base buried under the ice - and a long dead body still hot with radiation. Before Mercer and his colleague, the seductive Dr. Anita Klein, can investigate further, a flash fire engulfs the base, and they are ordered to evacuate. But their plane is forced to land when a bomb is discovered on board, and they must seek shelter from the murderous weather in a hidden ice cave. That's when they learn the startling truth. A powerful German corporation has launched an operation to destroy evidence of its Nazi past. But one of the mercenaries knows what's inside the boxes, and he plans to hold the entire world hostage - unless Mercer can stop him . . .
