Gu Yusheng, a grain station quality inspector, discovers during grain collection that Liang Fengnian's paddy moisture exceeds the standard, and learns that the drying ground is occupied by supplies, while the cooperative's dryer sits idle due to cost and personal relationship concerns. He insists on following standards, actively coordinates resources, and promotes public scheduling of the dryer at cost price, allowing farmers to use it fairly. As the drying ground is cleared again and the scheduling system gradually stabilizes, Liang Fengnian's grain successfully meets the standard, and Liang Xiaozhu also accepts standardized management. Ultimately, the dryer continues to operate, the drying ground resumes grain drying, and Gu Yusheng solves the practical difficulties of the farmers with patience and rules.
