Overview:

Stella is 6 but she is going to school for the first time. Happy, exuberant (maybe too much) she is a lovely child, but is often absent. Her parents say she is fragile. She tells her teacher, Céline, she fell when asked why she has a few bruises. Is it child abuse or real immune deficiency? The doubt is growing in the mind of those who meet the child. Worried, Céline notes every injury until the day the family moves without telling anyone.
