This is a history that spans half a century. In 1967, the US Navy's Second Medical Research Institute (NAMRU-2), based in Taipei, built a pure white building in Shuilin Township, Yunlin County, and began a seven-year research project. The research process has left residents curious and suspicious of the mysterious building, resulting in whispers and adults warning children to stay away. However, not much is known about the research project in Taiwan, as all the relevant data was taken to the United States with the end of the project. The film's director, Li Jian Cheng's father, was part of the research project at the time, so the whole process of filming was not only about unearthing the lost past, but also evoking the memories of the elders' youth 50 years ago.
