In 1993, Lin Haisheng, once despised by everyone, comes to his senses when his wife and daughter are pushed to the brink of despair and resolves to rebuild his family. With an exceptional ability to read the tides, fish schools, and sea conditions, he starts by catching crabs on rocky shores, repeatedly discovering rare seafood and gradually improving his family's once destitute life. As his reputation grows, Lin Haisheng transforms from a poor man scorned by the entire village into a skilled seafarer who can protect his wife and daughter and help his fellow villagers earn a living. Facing storms, competition, and repeated unexpected trials, he never forgets why he fights so hard: to keep his wife and daughter well-fed and warmly clothed, and to give his family a truly secure and prosperous life.
