The Bamboo House of Dolls

In the final stages of World War II, the Japanese troops in South West China rob gold from Chinese banks with the intention of shipping it to Japan. They also capture a number of young women, and imprison them in a concentration camp where they can rape these helpless prisoners. Among the prisoners are Hung Yu Lan, Hu Li Chu, Huang Hsia and three American Red Cross nurses, namely, Jennifer, Elizabeth, and Mary.
Chang, the camp cook, is actually a Chinese agent planted in the camp to help Hu Li Chu escape. Hu Li Chu is the wife of a Chinese army officer who recovered the stolen gold when he led his men in ambush against the Japanese. All his comrades were killed but before he himself died, he managed to hide the gold and reveal it’s hiding place to his wife. However, Hu Li Chu suffers partial amnesia as a result of the brutal treatment by Japanese soldiers, and she refuses to make an escape bid without Jennifer and the other four girls.
