Chenghua, aged 9, is preparing a school project on space travel with her best friend. She cannot find enough time to do this as she is constantly asked to translate for her parents. They do not speak French and are dependent on their child; they do not realize that they are placing too heavy a weight on her young shoulders.
Chenghua can take no more and tries to break free from her family. Her desire for space and natural enthusiasm will help her take those steps.
