Widowed fisherwoman Lin Yu raises her young son with leukemia. Desperate, she enters the forbidden sea and awakens an ancient golden dragon, gaining golden eyes and an undersea space. She collects sea treasures and antiques to raise money for his treatment. She faces bullies, greedy stepmother and schemes from a mining tycoon. She abides by marine rules and never chases ill-gotten gains. Chen Mo, from an antique clan, recognizes her talent and supports her. They join stone and treasure auctions, outwit traps in contests, represent the country in international events, expose overseas counterfeit plots and recover lost national relics.
