This is a century-old school and one of the city's model schools. The head teacher of Class 9, Grade 3, "Fan Yiben" (played by Alex Fong) led the whole class to a series of stories in the final stage of the college entrance examination sprint. The play is based on the most typical real themes in contemporary society, focusing on various situations from four different families. It truly reflects the stories of several groups of families in society. The main line is the tense countdown stage of four students preparing for the college entrance examination. Ren Xue (played by Lu Yi), the class leader, was forced by his father to study abroad, and ran away from home because of a quarrel with his father (played by Wu Gang). Lin Ye (played by Qiao Qiao), Ren Xue's best friend, gave up the college entrance examination because of her parents' divorce. He Fan (played by Wu Junyu), the study committee member. Because the family was preparing for college tuition, they were defrauded by profiteers. His father He Jianghai (played by Da Qin) was detained for injuring someone to protect his son, which led to increased pressure in life. Qin Peng (played by Tan Jiexi), the king of partial subjects. He is confident in sunshine and likes to play some pranks. His college entrance examination results are facing a crisis because of his off-topic composition. When these four students were on the verge of giving up the college entrance examination, the unique educational methods of teacher "Fan Yiben" and the students' own efforts finally solved various problems from their families and themselves. At the same time, this film is full of emotions between students who are in the budding of adolescent emotions, as well as the "contradictions" and "struggles" between students who are in the budding of adolescent rebellion and teachers. It fully depicts the common problems in contemporary families, and also reflects the pitiful hearts of parents and the gap between today's students and parents. It also explains the unique educational methods of teacher "Fan Yiben".
