One of our subs was missingThe nightmare fear of the U.S. had come true. One of our finest submarines, the U.S.S. Tampa, on a top-secret spying mission, had fallen into Chinese Communist hands. The Communists, fighting for survival in a savage civil war, now held not only the sub, the crew, and gutsy Commander Sean Murphy hostage, but U.S. power and prestige as well.America had one last desperate card to play. The most advanced submarine in the world, the still untried U.S.S. Seawolf, under the command of maverick daredevil Captain Michael "Patch" Pacino. The Seawolf had to steal back the Tampa from where it lay guarded by the entire Chinese fleet armed to the teeth with technology from the bankrupt Russians.
