Shen Zhou, a young man with a degree in aquaculture, returns to his hometown to start a business. Using scientific technology, he plans to build protective nets around the fishing village, but his conservative relatives stir up the villagers and persuade them to tear the nets down. A massive tide strikes alongside a shark attack, causing devastating losses throughout the village. Those who caused the trouble try to shift the blame, only to be exposed and humiliated by irrefutable evidence. Putting the past behind him, Shen Zhou leads the entire village in rebuilding after the disaster. However, the malicious troublemakers who refuse to change their ways ultimately end up behind bars. From then on, the fishing village embraces scientific and ecological aquaculture, achieving shared prosperity between its mountains and seas and revitalizing rural life.
