The Sea of Okhotsk north of the Japanese Home Islands is a cold and unforgiving place. Its icy, dark waters can change from a glass-smooth calm into a raging maelstrom in a heartbeat. The shores surrounding the sea, home to Siberian tigers and prowling wolf packs, are equally forbidding. Far from Mother Russia, beyond Siberia, it is a mostly forgotten land—even though it is the home of the Russian Navy's Pacific Fleet.

Mush Morton was a warrior without peer. At the helm of the USS Wahoo he completely changed the way the submarines fought in the Pacific War. He would relentlessly attack the Japanese at every opportunity, burning through his supply of torpedoes in record time on every patrol. Over the course of only nine months and five patrols, Morton racked up an astounding list of achievements, including being the first American skipper to wipe out an entire enemy convoy single-handedly.

At the top of the world… at the bottom of the sea… a war has begun. Below the polar ice cap, an American nuclear submarine moves quietly in the frigid water, tailing a new Russian sub. But the usual, unspoken game of hide-and-seek between opposing captains ends when the Americans hear sounds of disaster and flooding, and the Russian sub sinks at a depth of a thousand feet. The American sub rushes to help, only to join its former quarry in the deep. The situation ignites tensions around the world.

USS Teuthis Saturation Dive Team Officer-in-Charge (OIC) Mac McDowell is leading his submarine team on a mission to lay SOSUS arrays under the ice in the Arctic when they clash with a new Alfa-class highly automated Soviet submarine. Overwhelmed by mechanical problems, the Soviet crew abandons their sub near Pt. Barrow, Alaska. The Teuthis skipper launches DSRV-1 Mystic, so Mac and his crew can board the empty sub and gather intelligence. The arrival of an even more advanced Soviet sub leads to breathtaking underwater clashes with the specter of war looming.
