 It is 1980 and the USS Nimitz puts to sea off of Pearl Harbor for routine exercises. After encountering a strange storm and losing all contact with the US Pacific Fleet, nuclear war with the Soviet Union is assumed and the USS Nimitz arms herself for battle. However, after encountering Japanese Zero scout planes and finding Pearl Harbor filled with pre-World War II battleships, it is realized that the storm the Nimitz went through caused the ship to travel back in time: to December 6th, 1941.
