Sheng Lin, a fisherman who was betrayed by his brother-in-law and cheated out of millions in profit-sharing after years of fishing together, relies on his grandfather's surviving navigation journal to take his old fishing boat alone into dangerous deep-sea reefs. Every trip brings him catches of extraordinarily valuable and rare seafood. His ungrateful brother-in-law repeatedly follows him, lays ambushes, and conspires with black-market boat owners to steal his cargo. But unfamiliar with the sea conditions and driven by greed, he repeatedly sinks his boats and runs aground, ultimately suffering the consequences of his own actions. On one side is a hardworking fisherman making an honest living and receiving the ocean's generous gifts; on the other is a greedy opportunist whose schemes ultimately bring the sea's wrath upon him. Together, they set the stage for a thrilling maritime survival drama filled with raging waves and difficult choices that reveal human nature.
