After her family is forced to move by Canada's racist wartime policies, Michiko is the only Japanese kid at school. One nice thing is that she's a hit at the local baseball tryouts. There's just one problem: everyone thinks she's a boy. What is she to do when they find her out - do as she's told and quit, or pitch like never before? Maruno tells an almost uniquely Canadian story as we see how different cultural communities interact, as well as the challenges many first- and second-generation Canadians encounter, issues that are still relevant today.
