## Plot

In the near future, the world is at war: the USR (the Undersea Silence Revolution or Underwater Silence Revolution), a mysterious organization led by Admiral Red and his powerful submarine UX, wants to stop human exploitation of the seas, using cutting-edge technology to torpedo and sink many ships and ports. The world's navies unite and form the Peace-Keeping Navy (PKN) to fight against the "terrorists". Every major UN member contributes a submarine, although the Japanese entry is an old clunker, the diesel sub 707 commanded by Captain Youhei Hayami. When the inaugural meeting finally begins, Admiral Red and the UX come to disrupt the meeting with a spread of torpedoes; due to a lack of command procedure and an unwise tight grouping of the PKN vessels, they are unable to fight back without damaging their own craft. Arriving late in the battle, Captain Hayami deliberately steers the 707 into the way of a torpedo launched at the supercarrier that serves as the PKN's flagship. His ship is destroyed, but the flagship, Captain Hayami and the 707 's crew survive.
Six months later, Captain Hayami is given command of a completely new 707, and takes on a crew of old comrades and brand new cadets to battle Admiral Red once more. As the inevitable showdown draws ever closer, it becomes a personal battle between Admiral Red with his superior technology and USR's submarine fleet and Captain Hayami with his incredible submariner skills and loyal crew.
