Although the actual battle of the Coral Sea does not begin this standard wartime drama, there is plenty of action and suspense as the preparation stage of the battle is carried out. A submarine captained by Jeff Conway (Cliff Robertson) successfully scouts the location of enemy installations, ships, and subs and then starts to head back to friendly waters. Before chugging very far in that direction, the submarine is spotted and captured by the Japanese. The crew members are taken prisoner by an even-handed Commander Mori (Teru Shimada) and held on the Japanese forces' island base. While chaffing under a ticking clock as the day of the final confrontation draws near, an island woman is secretly enlisted to help smuggle out three of the prisoners. If they can make it off the island to their own base, then the all-important information on the Japanese positions will tip the scales in favor of the U.S. Navy. ~ Eleanor Mannikka, Rovi
