After the young and energetic art teacher Guo Yuntian (Yu Han) was transferred from a big city to Shuicheng Township Primary School, he discovered that Gu Amin (Huang Kunxuan), a "bad student" in the eyes of other teachers, was a painting genius. After investigation, he learned that Gu Amin's family was poor. Guo Yuntian began to take good care of him and often clashed with other teachers for him. The principal entrusted Guo Yuntian to select an art contestant to represent the school in the competition. Guo Yuntian strongly recommended Gu Amin, but was opposed by other teachers. After arguing with reason, Guo Yuntian finally failed to resist the mouths of everyone. With apologies to Gu Amin, he left Shuicheng Township with one of his paintings. After losing the election, Gu Amin died of liver disease due to sadness and long-term malnutrition. He didn't know that the painting he gave to Guo Yuntian as a memorial had won him world-wide honors.
