This story is about two people who have struggled for more than 40 years to remember Korean forced mobilizers in the northern Akita region. Ha Jung-woong, a Korean-Japanese who succeeded as a businessman thanks to his outstanding abilities and the economic growth of Japan after the war, and Juroku Chatani, a Japanese historian who has built a community culture village in the Akita region of northern Japan. Their efforts to unravel the mystery of the Hime Kannon statue built on Lake Tazawa and to commemorate the victims of Korean forced labor are still ongoing.
