Assassins from a Japanese society, Nakama, try to kill CIA agent Brad Dixon for hacking their blog site. He, his two attractive female helpers, and a navy officer struggle for their lives against Nakama assassins. Using NSA hacking programs they learn Nakama's intention is to recover a secret weapon that has slept since WWII on a sunken Japanese submarine near Adak Island in the Aleutians. They want it to deter nuclear threats by North Korea against Japan. Brad's team goes to Adak, dives on the submarine, and prepares to retrieve the weapon. Japanese divers arrive and secure the weapon on a boat on which they hold Brad and the navy officer hostage. The two men fight for their lives in a blazing gun battle. Then Brad makes a decision that, if it works, will keep the weapon from reaching Japan and threatening a war with North Korea.
