In Taisho period Japan where women are seen as only good for housework, nine students at an all-girls high school learn how to play baseball to prove that they can compete with the boys.

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.
