The Himeyuri Peace Museum tells the story of the Himeyuri Student Corps, a group of young schoolgirls who were forced onto the battlefield at the prime of their youth to treat wounded soldiers in the Battle of Okinawa during WWII. In recent years, the museum had been facing a serious problem: the exhibits were not getting through to the young people of today. To bring change to this situation, the museum boldly decided to renovate its exhibits to make the theme of war and peace more relatable for the younger generations. But as the museum staff, all of whom have never experienced war, set out on the arduous path to do just that, they are met with even more challenges. The museum staff dedicate themselves to find ways to revive the lost voices of the Himeyuri girls, which have the power to remind future generations of the horrors of war and the invaluableness of peace.
