In the documentary, 81-year-old Ni Cuiping told of the tragic experience of raped by Japanese invaders by turn when she was only 11 years old. She said bravely: "If I'm still alive, I will be a witness of Nanjing Massacre."

In the early morning on July 26th, Ni Cuiping came to Heping Cinema accompanied by her daughter. During the whole showing time, she was always weeping quietly. "Japanese invaders were very brutal", Ni pointed at her deeply sunk left collarbone: "This scar is the evidence of Japanese invaders' atrocities in Nanjing. On the day that they occupied Nanjing, I lost seven family members in one day. Through that massacre, I became the only survivor in my family."
