Humiliated by the family division, Lin Hai, taking his wife and daughter, was driven out of the Lin family, receiving only a broken sampan. Awakening the marine radar system, he can see through the seabed, detecting fish schools and treasures. Risking his life heading out to sea, he catches large yellow croakers, exquisite lobsters, and harvests deep-sea red coral, struggling from poverty to become a ten-thousand-yuan household, building brick houses and buying color televisions. Facing the constant coveting and scheming of his old family relatives and the open and hidden plots of opponents, Lin Hai resolves them one by one with his skills and courage, vowing to sail into the distant sea and carve out a magnificent life of his own.
