When 9-year-old orphan Oliver Twist dares to ask his cruel taskmaster, Mr. Bumble, for a second serving of gruel, he's hired out as an apprentice. Escaping that dismal fate, young Oliver falls in with the street urchin known as the Artful Dodger and his criminal mentor, Fagin. When kindly Mr. Brownlow takes Oliver in, Fagin's evil henchman Bill Sikes plots to kidnap the boy.

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.
