故事发生在大正十四年,那是一个女子地位极其卑微的年代,除了在家相夫教子,女孩们几乎没有别的出路。然而,就是在这样的年代中,不愿为命运所桎梏的大小姐小笠原晶子(中原麻衣 配音)下定了一个可以说是疯狂的决心——成立一支女子棒球队。 作为晶子的好友,个性单纯开朗的铃川小梅(伊藤加奈惠 配音)当然要鼎力相助。同时,头脑灵活的川岛乃枝(植田佳奈 配音)、威信极高的班长宗谷雪(能登麻美子 配音)、运动健将月映巴(甲斐田裕子 配音)和其妹妹月映静(喜多村英梨 配音)等人也都逐渐加入了晶子的棒球队,在众人的非议声中,一支特殊的女子棒球队就这样成立了。这群走在时代前沿的女孩子们,会有怎样又笑有泪的经历在等着她们呢?When a local player arrogantly states that girls should become housewives instead of going to school, teenage firebrands Koume and Akiko respond by forming their own baseball team. It's shocking. It's scandalous. And yet, in a nation in which almost anything seems suddenly possible, it may just be the start of something greater than any nine girls can imagine.
