A woman's struggle for equality in Japan in the 1880s. Eiko Hirayama leaves Okayama for Tokyo, where she helps the fledgling Liberal Party and falls in love with its leader Kentaro Omoi, just as the party is being disbanded by the government. Eiko and Omoi are jailed because of a fire at a factory instigated by Chiyo, a servant girl from Eiko's home in Okayama, who was sold to slavery. A few years later the 1889 constitution is proclaimed, Eiko, Omoi, and Chiyo are pardoned, and the Liberal Party is reinaugurated. However Omoi does not campaign for women's rights.
