The story is about the plight of Japanese women who served the US soldiers during the second World War. After the war, they had to pay someone who knew English to write love letters to their former lovers to ask for money to survive.
Considering that it was a debut effort by Tanaka Kinuyo, it was not too bad! Thought it could be improved by deleting unimportant scenes which did not contribute to the main storyline.
