Artists, architects, writers, actors, curators, and scholars work together in an investigation group, and their investigation on marginalized or invisible women focuses on Japan-based writers and politicians. Of Girls targets Fumiko Hayashi, a feminist writer who wrote a semi-autobiographical novel, and Yuriko Miyamoto, who pursued socialist ideals and homosexuality and worked for the liberation of women. The investigation is performed by moving between the library and the Tokyo house designed by Fumiko, double screens designed as a moving border, and moving cameras. It also combines debate, reading, and performance to show the paths of two women and the power of their words and writings.
