Female lead Shen Qinghe returns to her hometown to transfer three hundred acres of muddy wasteland, painstakingly spending six years building the "Qinghe Bay" clear-water Chinese mitten crab brand. Relying on superb technology and standardized management, she turns an unpromising barren pond into a profitable base. Village branch secretary uncle Shen Dewang, co-opted by villagers' jealous emotions and using family affection as a hostage, takes the lead in forcing Shen Qinghe to withdraw from the pond dike. Under the circumstance of only recovering the land during contract signing, he connives at his son Shen Yao and middleman Qian Sihai scheming, hoodwinking villagers into pooling funds, intending to collectively take over the crab pond and sit back to enjoy the profits.
