In 1988, Fu Wan, who had suffered endlessly before passing away, unexpectedly experiences rebirth, returning to the day she was pressured by her in-laws to hand over a precious treasure. Awakening her seafood-gathering assistance ability, she decisively divorces her ex-husband and returns to live with her family of origin alongside her daughter. With misfortune in her past life, she is determined this time to reverse her fate, heading into the sea to search for marine products and harvest treasures, accumulating wealth through selling seafood. She wholeheartedly protects her family, supports relatives, and strikes back one by one at all the relatives and friends who used to bully her. Working hard all the way up, Fu Wan transforms from a looked-down-upon single mother into a wealthy local merchant, also winning widespread recognition.
