This is a film that captures the performance of the play "Isshogai" in 2017 by "Nijiro Mocha," a theater medium produced by actor Maruwaka Kaoru. Set in Osaka and Tokyo, the play depicts two stories that transcend time and space: the protagonist Mayu's high school days, when her happy life changes completely, and the life she follows after moving to Tokyo, all on the same stage, depicting what disabilities are, and what prejudice and discrimination are.
