Shigeko and Midori, star swimmers at the renowned Kirishima Girls’ School, are training relentlessly with their sights set on the Los Angeles Olympics. But for the past week, Shigeko has been absent from practice. Her father has fallen ill, and to support her family’s struggling finances, she has secretly taken a job at a trading company. When Masao discovers this, he asks Midori to convince her to return, but soon the school learns of her secret. The students rally to raise funds, though the principal refuses their help, promising instead to handle the situation himself. Shigeko resumes training and travels to Tokyo for the qualifying meet. She touches the wall first in the 100-meter freestyle—only to receive news of her father’s passing. Overcome with grief, she collapses, cared for by Midori, whose own exhaustion leaves her finishing fourth. Despite these hardships, their prior accomplishments earn them a place on Japan’s Olympic team.
