In the early 1990s, Chen Shouhai, a fisherman from Haisha Town, finds himself in difficult circumstances but never abandons his original values. Amidst raging waves, he kindly rescues an abandoned baby girl named Niannian and raises her as his own, showering her with loving care. Pure-hearted and remarkably perceptive, Niannian can sense the rhythm of the tides and see beneath the ocean's surface, guiding them toward abundant fishing grounds. Meanwhile, Chen Shouhai keeps his feet firmly on the ground, leading the villagers to work together and strive for a better life. Through hard work and lawful business practices, they gradually grow from gathering seafood with a small wooden boat to establishing cold-storage facilities, modern deep-water berths, and a fleet of ocean-going vessels with a combined capacity of tens of thousands of tons.
