Spring in Cowboy Class tells the story of Matthew, an unemployed music teacher, coming to a boarding school and facing a group of lawless students abandoned by adults. Matthew used pure music to awaken students' buried love and soothe their wounded hearts, thus changing their own destiny.
The first child Matthew saw when he came to school was Babineau. Babineau is waiting for his father to take him home at school, but Babineau is an orphan. His parents died in the war, but the teachers hid the fact from Matthew and cheated Babineau. His father will take him home on Saturday.
In boarding schools, the principal's expression is rigid and boring, and abuse and corporal punishment are the only ways of communication between teachers and students. However, after the appearance of the lovely new policeman Sima Xiu, the chaotic and violent school atmosphere changed. Teacher Matthew chose to influence this group of problem of juvenile with music. Inspired by the charm of music, the sunshine in children's hearts slowly bloomed. The gloomy school has changed inadvertently, and these so-called juvenile heart problems have been purified.
The ending of Spring in Cowboy Class is not so satisfactory. The choir was forced to disband and Matthew was forced to leave school. At the last moment when he left school, Matthew took away Babineau, a child who would wait for his father to pick him up every Saturday. When Matthew left school, Babineau ran to Matthew with the bear in the bag and carefully told Matthew to leave here. Matthew got on the bus, got off the bus again, and took Babineau on the bus. At the same time, a voice-over appeared in the film: Babineau's persistence and waiting were worthwhile, and Matthew left on Saturday.
During his months in Matthew's school, in Barbeno's heart, he thought that this gentle music teacher could pick up his father on Saturday. Matthew is kind-hearted and unwilling to give up Babeno. Seeing Babineau's eyes reveal dependence and trust, Matthew relented and jumped out of the car to take Babineau away.
