Rural teacher Jiang Shu moonlights as a food delivery driver to subsidize impoverished students. When delivering stomach medicine to Shen Corporation President Shen Sinan, he is publicly humiliated by Xu Qingqing, who tramples the medicine to pieces and maliciously frames him. Recognizing that the delivery driver before him is his former mentor, Shen Sinan is deeply shaken. As surveillance evidence is exposed, the turmoil does not end; holding a grudge, Xu Qingqing bribes internet trolls to cyberbully Jiang Shu. A group of students who succeeded thanks to Jiang Shu's kindness step forward to uncover the rumors. Putting aside personal gratitude, everyone builds a transparent and open student aid system, using rules to protect the educational path of underprivileged students in the mountains.
