At a top-secret facility in Alaska, a destructive nuclear substance; powerful enough to destroy the world, is America’s last reminder of the Cold War. When a mission to retrieve a sample wipes out an entire town, a master plan is hatched to destroy it once and for all. A team of experts will ship a supertanker of the deadly matter to the deepest part of the ocean, fill it with concrete, sink and entomb it on the sea floor forever. Sounds simple? When an earthquake strikes and a rogue wave leaves the ship unstable, there’s only so much time to sink the ship before the world is destroyed.
