The story is about the legendary baseball player Noguchi Jiro (1919 - 2007) who was regarded as the pioneer Nitouryuu (a baseball player who could play as both pitcher and fielder) in Japanese baseball history. His excellent pitching skills placed him as one of the best pitchers before WWII and his strong stamina gave him the nickname of "Tetsuwan" (Iron Arm). He had 237 wins and earned 830 base hits in his entire career. Together with his elder brother Akira and two younger brothers Noboru and Wataru, the Noguchi siblings who were all professional baseball players, had a deep bond between themselves as they lived through the turbulent times before and after the war.
