Shen Guiying dedicated half her life to her family, selling her house to pull together a down payment, taking care of chores and raising her grandson, only to be spurned by her daughter-in-law Zhao Manli, her in-law Liu Fengqin, and her son Lin Zhiyuan. After her birthday was ignored and the compass left by her husband was smashed, her heart grew completely cold and she left home. Returning to the old dock, she relied on maritime skills practiced in her early years to publicly expose a fraudulent fishmonger, and repaired old boats to catch a premium large yellow croaker. Not only did she help an upscale corporate group defuse a dinner party counterfeit goods crisis, but she also won the hearts of the dockworkers and drove middle-aged women to start businesses, rising from a mistreated nanny to a maritime queen respected by all.
