Kyoto, Japan. 1936. While a shroud of impending unrest hangs over Europe, in Japan the number of Yakuza members is close to outnumbering the Japanese army. In a government experiment, a group of geisha ladies are recruited to inform on the conversations they observe between the murderers and politicians. However, as untrained spies the geishaâs actions result in one of their memberâs brutal and bloody murder.
