Shen An is reborn on the very day his biased family divides the household and kicks him out, leaving him with nothing but a dilapidated fishing boat and five yuan. In his previous life, he trusted the wrong people, was cheated out of his money through gambling and business ventures, and caused his wife, A Xiang, to endure endless hardship before dying young. He himself ended up destitute and died miserably at the docks. Given a second chance, he resolves to protect A Xiang. Drawing on his memories of his previous life, he learns the resources hidden in the tidal flats and offshore islands, gathers seafood, catches fresh fish, and sets up tidal barrier nets. He also ventures into the mountains to collect local produce and trades fish maw and medicinal herbs, finding multiple ways to make money. When greedy relatives come demanding his earnings and bad friends set traps to cheat him, he fights back with the household division agreement and complete financial records, ensuring that the wicked suffer the consequences of their own actions. He helps his aunt through hardship, supports his abandoned grandmother, and eventually welcomes his biased parents back into his life so they can enjoy their old age in peace.
