In 1917, Taiwan grapples with a harsh drought and famine during Japanese rule. The impoverished inhabitants of Chianan Plain endure hardships, their existence revolving around the relentless task of fetching water. When Yoichi Hatta, a Japanese engineer, proposes a bold irrigation project to transform the region, skepticism runs high among the locals. Xu Yingzhe, a farmer's son, challenges the community's dismissal of Hatta's vision, seeking to understand the potential behind the seemingly outlandish plan. While Hatta's idea appears far-fetched, it holds the promise of alleviating the arduous conditions faced by the Taiwanese populace.
