A beautiful but sad romantic melodrama about three sisters who are uninhibited, pure and lovely, and who stand tall like the peaks of a place that has endured the winds and snow of love! Eisuke Taniguchi (Shimizu), president of Towa Electric Works, has three beautiful daughters. The eldest, Kozue (Todoroki), is an intelligent and dynamic modern girl, the second, Yoko (Otowa), is a modest girl with Japanese tastes, and the third, Hanayo (Wakayama), is a mischievous girl who has not yet lost her schoolgirl temperament. All three have feelings for Kiichiro Matsuzaki (Uehara), the president of a magazine company. He was married to Kozue, the eldest daughter, by agreement between their parents, but it was Yoko whom he loved, so he asked her to end her engagement to him.
