As a super typhoon approaches, new agriculturalist Lin Chen notices that the corn is about to suffer an outbreak of ear rot. He goes door-to-door to urge farmers to harvest early, but is slandered and driven down in price by his cousin Lin Mengyao, who wants to gain traffic, inciting the whole village to be hostile toward him. The typhoon makes landfall early, large areas of corn are soaked and moldy, the grain merchant who promised high prices loses contact, and the villagers fall into despair. Letting bygones be bygones, Lin Chen uses his own startup capital, opens the drying tower to lead everyone to harvest through the night, and classifies the moldy grain to recover losses. As the storm subsides, everyone recognizes Lin Mengyao's profit-driven true face, and Lin Chen teaches the whole village the principles of honesty and conscience with practical work.
