Plot summary for
The Final Countdown (1980)
An American nuclear aircraft carrier and its crew are caught in a classic dilemma when a supernatural storm sends them back in time just before the Japanese assault on Pearl Harbour. Written by Keith Loh {loh@sfu.ca}
The USS Nimitz, a modern-day nuclear aircraft carrier, is drawn through a time warp from 1980 to a couple days before the Japanese assault on Pearl Harbor, and the crew must decide whether to launch a preemptive strike against the incoming Japanese carrier fleet with their more advanced air wing, or allow history to take its course, which might not happen since they had rescued Senator Chapman, who disappeared shortly before the attack, from his death. Written by Jeff Cross {blackjac_1998@yahoo.com}
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.
