Life becomes more complicated when a troublesome pupil, Sasha, arrives at the school. She becomes emotionally sympathetic to the boy, but her own son is antagonistic towards him. The boy's mother appears to go missing for days on end and the emergency contact turns out to be Mathieu, a former acquaintance of the boy's mother who now wants little to do with her. Sasha, however, seems to be close to Mathieu.
As the other teachers appear to give up on Sasha, Florence becomes more deeply involved with him, even seeking out his mother to plead with her to see her son. And to further complicate matters, Florence starts to have romantic feelings towards Mathieu.
Pressure builds and it all becomes too much, with Florence starting to question her vocation as a teacher. As the children prepare to present their end of term play to parents, which Florence played a large part in developing, will she stay or leave?
