Toimintaa Tyynellä merellä

World War II rages across the Pacific and Lt. Cmdr. Duke E. Gifford is in the thick of it. He evacuates children from enemy-held islands. Oversees the development of torpedoes at Pearl Harbor. And prowls the depths in the submarine Thunderfish for a chance to aim his improved "tin fish" - torpedoes - at the enemy. John Wayne plays Gifford in Operation Pacific. "I'm no theory man. I'm a line officer," Gifford barks. He backs it up with lots of bite in several feverish sea battles. He's also a man of heart with a loving wife at home (Patricia Neal). (jakelijan virallinen teksti)
