Lin Canghai gave his all for his son Lin Haisheng, yet was long mistreated by him and his daughter-in-law. On the anniversary of his wife's death, Lin Canghai completely broke ties with his son because his sacrificial offerings were destroyed, and was driven out of his home. Disillusioned, he took young fisherman Zhang Xudong to return to the ocean, relying on his superior experience and courage to successively capture premium seafood and priceless edible bird's nests at Black Stone Reef and a top-secret isolated island, rapidly attaining great wealth and building a villa. Learning that his father had struck it rich, the greedy Lin Haisheng and his wife sneaked into the villa to steal at midnight, triggering the alarm and being caught on the spot and imprisoned. Ultimately, Lin Canghai severed relations with his biological son, taking in the loyal Zhang Xudong as an adopted son to inherit all of his family property.
