On September 2, 1945, the Japanese surrender ceremony in WWII was held. Japan signed a capitulation to the United States, the Soviet Union, Britain and China, and history should not be forgotten. The "comfort women" system is part of the brutal memory of Japan's war of aggression. Not long ago, several victims of the "comfort women" system during the Japanese invasion were newly identified in the mountainous areas of Hunan. Their personal experience revealed the tragedy of "comfort women", which happened more than half a century ago. The sinking of the country and the national crisis have brought serious disasters to the majority of women in China, and the special group have also prompted themselves to awaken step by step. They have always been firmly tied to the destiny of the motherland. Through 15-year interviewing and investigating, this film presented to the audience the strength of women in the War of Resistance.
