After returning to his hometown, university graduate Chen Mo rents a fishpond to raise eels. His eco-friendly farming techniques begin to show promising results, but he repeatedly faces harassment from village bully Liu Jinbiao, who keeps seizing resources and secretly setting traps to sabotage him. Faced with one crisis after another, Chen Mo remains calm, cleverly sees through every scheme, and overcomes each obstacle. Once he has established himself, he takes the lead in founding an aquaculture cooperative and freely teaches villagers his eel-farming techniques. Together, they develop the industry, build an eco-friendly eel production chain, lift the entire village out of poverty, and embark on a path toward shared prosperity and increased income.
