This film is a military documentary told from the point of view of the crew of the aircraft carrier the Fighting Lady -- a pseudonym for the Yorktown. Scenes highlight the functions and duties of The Fighting Lady and crew activities, and maps illustrate the movement of the Pacific fleet and its engagement with the Japanese in 1943 and 1944. Footage shows the following: A-24 Dauntlesses, TBF Avengers, Hellcats and other aircrafts as they flew out to the carrier, and the August 30, 1943, strafing and bombing mission over Japanese - held Marcus Island -- from preparation on the carrier to debriefing. Later scenes cover 1944, when the U.S. forces took Kwajalein Island, the Marshall Islands, Truk Islands, and Caroline Islands through air assaults and troop landings. Mitsubishi Zero-Sens (Zekes) engaged the U.S. Navy assault force and the ship squadron returned to the Marshall Islands for repairs, munitions, and rest and recreation. En route to the battle area, the Fighting Lady encountered and downed a Japanese reconnaissance plane. On the eve of battle, sailors attended church services. Prior to the U.S. assault, the Japanese attacked the U.S. squadron and U.S. planes took off for the Marianas and the Guam Islands where they successfully fought at the Tinian and Mariana Islands. The Japanese and U.S. task forces then fought in the Philippine Sea, where planes engaged in dogfights while ships performed evasive maneuvers. Final scenes show U.S. casualties buried at sea.
