The author of C.L.A. W. (1976) and Quicksilver (1976) comes up with a tight and tense WW II thriller--all about a band of Japanese-American navy men picked to sabotage Japan's dangerous progress toward production of a jet fighter plane. In the middle of the Second World War, as Japanese and American forces battle toward an obscure outcome in the Pacific, American intelligence discovers that the enemy is well on the way to producing a jet-powered fighter that will render American planes totally ineffective. The only apparent weakness in the Japanese threat is their reliance on a single factory to produce specialized steel capable of withstanding the enormous heat generated by the new jet engine. That factory is in Ringo, an isolated coastal village, where the American Navy lands a band of nisei in imperial uniforms from a disguised submarine. The infiltrators are so convincing that they actually enlist the assistance of the local defense forces on their way to blow up the plant. But just as it seems they have pulled off the outrageous stunt, they realize they have blown up the wrong plant and have to return without their handy explosives. The return visit gives Lieutenant Mara a chance to revisit the lovely daughter of the local army commander. The wooden dialogue is irritating, but it does not cripple the hectic, nerve-wracking action.
