国中毕业之后，热爱棒球的少年泽村荣纯（逢坂良太 配音）准备放弃理想，和朋友们一起在家乡的高中完成学业，然而，此时，泽村却收到了青岛高校棒球社副社长高岛礼（内山夕实 配音）的邀请，邀请他加入棒球队。要知道，青岛高校可是棒球远动员们心目中的圣地，无数前途无量的棒球选手们出自这所学校，泽村接受了这千载难逢的机遇。在球队里，泽村结识了一群志同道合的朋友们，心直口快大大咧咧的御幸一也（樱井孝宏 配音）、外表冷漠内心单纯的降谷晓（岛崎信长 配音）、身材矮小却实力强悍的小凑春市（花江夏树 配音）、看似腹黑却十分温柔的仓持洋一（浅沼晋太郎 配音），一行人为了完成称霸甲子园的梦想而不断挥洒着汗水，挑战着自我。
