Yuki has been married for ten years to her husband, who runs a small construction company. Together with the young workers at the site, she has led a modest yet warm married life. However, her husband's priorities have gradually shifted, focusing more on management and client entertainment than on the job site, and his spending has become increasingly reckless. Sales are rising, but the number of job sites has increased, placing even heavier burdens on the workers. Pushed to their limits by the harsh conditions, the frustrated young laborers turn their frustrations toward Yuki.
