In 1997, Chen Jianghe, a young man who failed the entrance exam, refuses to accept his fate. He transforms silkworm pupae, considered chicken feed by the villagers, into an irresistible delicacy: crispy, fragrant giant pupae. Despite family pressure and public ridicule, he wins over the market with his exceptional product quality, only to face a joint assault from rivals and industry monopolists that threatens to cut off his supply. Using his intelligence and determination, Chen Jianghe breaks through the crisis, vowing to lead his fellow villagers toward shared prosperity and achieve a spectacular transformation from cocoon to butterfly.
