In a coastal fishing village in the 1980s, Jiang Chuan ruined his family through alcoholism in his previous life, failing his wife, Su Wanqing, and his ailing sister-in-law, Su Nianyao. Reborn at a critical turning point, he vows to change his ways. Drawing on his family's ancestral knowledge of coastal foraging, he works diligently, gathers seafood, develops aquaculture, and establishes a local processing factory. Overcoming one obstacle after another, he devotes himself to treating Su Nianyao and supports her studies until she achieves the highest score in the county. He also leads the establishment of a fishing cooperative, helping the entire village prosper together. When outside merchants resort to unfair competition, he upholds honest business practices and protects his industry and fellow villagers through lawful channels and reasonable means, staying true to his original aspiration of achieving prosperity through hard work and sharing wealth with everyone.
