Chen Hai once relied on an old nautical chart left behind by his father to lead the Fenghang into storms and rough seas, returning with a boatload of fine crabs. But just when he had achieved success, his business partner, Meng Defa, pushed him off the boat. With his mother seriously ill and his family desperately short of money, Chen Hai refused to accept his fate. Instead, he took over an old, dilapidated fishing boat and set out to sea again. Facing treacherous currents, storms, and the schemes of rival fishermen, Chen Hai uses his experience and courage to turn his fortunes around, making those who greedily seized his gains pay the price.
