This Hungarian film full of children's voices and music uses a refined sketch-style story to raise many serious questions, such as the relationship between the individual and the collective, such as the choice between interests and truth, such as what kind of invisible field makes people last for a long time. Participate in and maintain the lie, who should feel guilty and who should bear it. The child and the child's voice interpret the story into a "fairy tale". The film deliberately omits a lot of ups and downs, and also deliberately does not show the possible follow-up and consequences. Everything until the teacher loses, showing a victory of sunshine, innocence and pure heart. But among those omissions and blanks, there are actually more terrible things that have not been presented - reality is not a fairy tale
