In Japan 70 years ago, there were women who set off for the battlefield of their own will. In 1931, Amano Kiyo (Matsushima Nanako), a student from Saga, has been inspired by a nurse who provided care for her mother, Kinue (Asaji Yoko), who was once hospitalised, and that becomes her dream. Wanting to be of use to the country even though she is a female, she decides to be an army nurse. Kiyo goes through hard training and graduates from nursing school without a hitch. She receives the draft papers and goes across to Manchuria along with her junior, Mabuchi Haru (Takanashi Rin) and others as she is sent off by her grandfather, Daisuke (Yamazaki Tsutomu), and mother. However, what awaits them is a harsh environment that exceeds expectations. It is far removed from the Red Cross’ conviction of the “spirit of benevolence”. They are in the line of fire and their lives always in danger. Every day is spent nursing so many injured soldiers that they are short-handed, and sleeping like a log. One day, Nakagawa Wataru (Nishijima Hidetoshi) of a Manchurian settlers community brings in injured people. One of them is his elder brother, Hikaru (Akai Hidekazu). The other patient is a Chinese called Sun (Kashikura Yuta). Kiyo persuades the military physician, Otake Hideyo (Shofukutei Tsurube), and provides Sun with medical treatment. But some incident leads to this matter being exposed by Lieutenant Colonel Kurahara (Hashimoto Satoshi), who is in charge of the hospital. After that, Kiyo, who has finished her 18-month stint, returns to Japan temporarily with some sense of purpose. She has fallen in love with Nakagawa and makes the decision to live in the settlers community. They get married and she then gives birth to their son, Hiroto (Kudo Asuka). In the midst of their happy days, the war intensifies and they start to find themselves at the mercy of the times.
