在这部潜艇特攻队战争片中,该片纯属虚构。1941年12月6日，日本偷袭珍珠港的前夕,日航空母舰“Hiranamu”，接令全速前往偷袭美军珍珠港。 途中，美国潜艇“海蛇”号的指挥官克里斯沃伦，截获日军秘密偷袭珍珠港讯息，他试图向基地发出警告最终失败。 第二天早上，12月7日，艇上的人接听到珍珠港被轰炸的消息，克里斯沃伦决定制定计划，率领潜艇攻击返航日军航母舰队，最终将其消灭。
On December 6, 1941, Captain Yamanada of the Japanese aircraft carrier "Hiranamu", orders full steam ahead for Pearl Harbor. His ship encounters and sinks an American yacht and the single survivor, Sue Curry, is rescued by an American submarine, the "Sea Serpent", commanded by Commander Chris Warren. He hears her story and attempts to radio a warning to Pearl Harbor. Yamanada, hearing the signals, orders the airlines jammed, and then sends his son into the air to sink the sub. The attack fails, after the sub makes a crash dive, but they fail in their warning attempts. The next morning, December 7th, the men on the sub hear the story of the bombing of Pearl Harbor, and devise a desperate plan to sink the Japanese carrier by letting the carrier know their position. The carrier comes in search of the submarine.
