The Mitsubishi A6M5 fighter plane (the "Zero") was Japan's most valuable weapon during World War II. This documentary examines the notorious plane's history and takes a look at the only existing Zero that can still take to the skies. It also tells the life story of the Japanese fighter pilot, Capt. Massager Karate, who shot down Pappy Boynton. Karate's handbook and family album are included as well.
