Born to a poor family in Yamanashi prefecture, in the year of 1903 at the age of 10, Muraoka Hanako was accepted by a Missionary school in Tokyo. It was her father's Ando Kippei, greatest wish that his daughter gets a higher education. The Missionary school was attended by daughters from noble families, and as a charity case, Hanako was reminded by her father to never be inferior to her rich schoolmates. As the classes were carried out in English, Hanako faced a culture shock when she started school. Unable to understand the teachers nor able to grasp the conversation of her peers, Hanako resolved to work really hard at her studies.

This drama follows Hanako from her childhood, through her years at the missionary school, to her life as a school teacher and finally as the translator of L.M. Montgomery's "Anne of Green Gables".
