During the off-season, seafood trader Chen Feng offers to purchase Black Reef Village's seafood at a high guaranteed price and signs a contract after paying an advance deposit. When market prices soar, village chief Lin Changshui tears up the agreement and demands a higher price. Chen Feng braves a dangerous cliffside path to secure the rest of the supply. He warns the villagers in advance about an impending red tide disaster, but they are deceived by a con artist and refuse to evacuate. When the red tide strikes, tens of millions of yuan worth of seafood catches rot, and the swindler flees with the money. The entire village regrets its decision. When the villagers come to Chen Feng for help, he buys back their damaged fish at the original price and entrusts the village's seafood production and sales to Uncle Laogen, establishing an ironclad industry rule based on integrity.
