The entire Soviet Atlantic Fleet is ordered to hunt down the submarine and destroy her at all costs. The Americans are determined to find her first and get her safely to port in the intelligence coups of all time. But the Red October has a million square miles of ocean to hide in and a new silent propulsion system that is impossible to detect. Or is it?
