After the Japanese kidnap two Korean teenagers and take them to a comfort station to join other girls who are serving as sex slaves, only one of them survives. Decades later, the elderly woman tries to reunite with her friend's spirit.

"Spirits' Homecoming, Unfinished Story" is part dramatization and part documentary. The film contains scenes from the movie “Spirits’ Homecoming” and testimonials by comfort women who were enslaved by the Japanese Imperial Army during World War II.
