一場平凡的校園爭鬥引發了對教育體制的質疑。一位老師因課後補習問題與學生發生衝突，而一位母親為此展開了激烈抗爭。最終，他們的抗爭雖然無法改變教育體制，但在他們的努力下，學生的純真笑容依然閃耀著希望。
Xie Zheng-Jie (Jay) is a senior in Taipei Municipal Li Ren Junior High School. He has to take the national senior high school entrance exams in the near future. One day, a school inspector from Taipei Education Bureau abruptly goes to Li Ren and tells them that there is a report on Mr. Zhan, a math teacher in Li Ren Junior High. After hearing this, Mr. Zhan is very angry. After Jay refuses to participate in Mr. Zhan's cram school, he is forced by Mr. Zhan to move his desk to the hallway outside and participate in the class from the hallway all day long. Mr. Zhan humiliates Jay's mother in front of Jay. Jay shoves Mr. Zhan, which causes a small physical altercation between the two. This leads to a conflict between Jay's family and the school. Jay is also given the elbow by other students. All of these consecutive incidents cause Jay to think of the real meaning in his daily routine - taking tests, going to cram school, studying hard, and what he really needs in his future life.
