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.

Rosemay, 16, lives in a foster home and only joins her biological family for the vacations. One day, her father is not there to welcome her as planned. Moreover, he does not reappear and seems to have evaporated. Her questions are met with lies, and Rosemay can only rely on her intuition.
