The small port town in Brittany in this movie has its charms, but they are largely invisible to the children growing up there. In the first place, they are deeply disturbed at the sudden death of an elderly woman who is one of their favorite teachers under what appear to them to be suspicious circumstances. They launch an investigation and start a little newspaper to report their findings in, as a result of which the workings of their little town are made extremely clear. When "suspects" refuse to cooperate with them, they persecute him (or her) with pranks until they do. Naturally, their teacher's replacement has her work cut out for her, but she eventually accomplishes this by taking an interest in her predecessor and the student's investigations.
