Synopsis：After being betrayed and wiped out by his own cousin, Lin Ye builds a powerful fish-tracking system from scrap, determined to turn the tide at sea. With a nearly bankrupt crew, he easily locks onto massive deep-sea shoals and reverses their fate. But once they cross into unfamiliar waters, the device picks up an eerie signal—down in the dark ocean floor, Lin Ye is no longer just hunting fish, but a mysterious force that may soon be hunting him.
