Shiro Kaieda is appointed the captain of Japan's first nuclear submarine, jointly built by Japan and the United States in top secret. However, he and his 76 crew members go rogue in this story that delves into themes of nuclear war, international politics, and world peace.

Yamato submerges in the cold, deep northern seas with Mozart's music echoing. The nuclear-powered submarine, named the “Great and Powerful Peace,” overwhelmed the U.S. Seventh Fleet in the Battle of Tokyo Bay and set course for New York. As it approached the Bering Strait, the border between the U.S. and Russia, a submarine loomed behind Yamato... “Sink the nuclear terrorist Yamato!” It is a cutting-edge U.S. submarine, far superior to Yamato, sent by the U.S. President Bennett. At the same time, a general election is held in Japan to dissolve the House of Representatives. Prime Minister Takegami announces his support for Yamato, and the two will share the same fate, whether they remain or sink. Will Shiro Kaieda be able to overcome the greatest challenge of the voyage? Under the aurora borealis, in the Arctic Ocean with floating ice floes, the curtain rises on the battle to be fought.
