A massive blizzard is about to block the mountains, and buyer Lu Zheng offers a guaranteed base price of thirty yuan per catty for white fungus, coming to purchase it in person. Blinded by profit and instigated by Wang Dabiao, Shangshui Village is certain prices will rise after the snow, tears up the contract, and refuses to ship their goods. Meanwhile, Li Laogen, the village chief of neighboring Xiagou Village, sees through the risk, decisively signs the agreement, and rushes to harvest the white fungus overnight. The snow arrives right on schedule, and the mountain roads are completely sealed. All of Shangshui Village's white fungus freezes and rots, exceeding standards for bongkrekic acid, leaving the goods stuck in their hands. Xiagou Village, which honors the contract, seizes the opportunity and obtains investment to build a constant-temperature base. A storm reveals the nature of human beings.
