Former cruise ship chef Shen Yu is betrayed by his cousin Lin Xiangdong and kicked out with only 120,000 yuan. He leases an abandoned alkaline pond in the village and joins forces with technician Gu Lan to successfully raise high-quality sea fish in inland saline-alkali water. After Lin Xiangdong's fish ponds suffer a collapse in quality, he resorts to poisoning them and ultimately lands in prison. Zhao, an aquatic industry tycoon, hijacks the poisoned ponds and blocks cold-chain logistics to suppress Shen Yu, only to be countered by Shen Yu's use of official distribution channels and biodegradable technology. In the end, Shen Yu buys back the old ponds at a low price and transforms them into an aquatic resort, bringing prosperity to the entire village while achieving success in both business and love with Gu Lan.
