Lin Chen, a lowly fisherman, is drained of all his earnings by his cousin Dylan Hale to pay for his seriously ill sister's medical bills, only to be kicked out of the house. He resolutely ventures into the dangerous deep-sea restricted zone recorded in his father's notebook — the Dragon Abyss, where he obtains sky-high value treasures in a desperate situation and saves female CEO Sloane Voss. The villainous Dylan Hale and his wife team up with bully Zhang Hao to set up an ambush to rob and kill Lin Chen and seize the treasures, only to anger the ancient patron deity the Sea Dragon King. At a critical moment, the fish-scale pendant left by Lin Chen's father awakens its divine power, forcing the Sea Dragon King to submit. In the end, Lin Chen turns the tide, conquers the deep sea side by side with Sloane Voss, reaps both career success and love, donates the one-of-a-kind treasures to the country, and achieves great fame and success.
