Raised in Japan, Yukiko’s education was made possible by a Taiwanese benefactor. As Expo ’70 nears, she becomes a hostess, determined to find her long-lost benefactor. Her search takes her across Osaka, Kobe, Nara, and Hokkaido, but every lead vanishes as quickly as it appears. Set against the 1970 Osaka Expo, this film stars Taiwanese-Japanese singer Judy ONGG, seamlessly blending music, dance, and documentary elements.
