Chen Shoutang returns to his hometown to take over the family fishpond, which his family has protected for generations. Rare ancient fish thrive in its waters, and after establishing fishing rules, he attracts numerous fishing enthusiasts. However, various investors and ill-intentioned individuals set their sights on the pond, repeatedly plotting schemes to destroy it. Chen Shoutang joins forces with the entire village to protect their ancestral property, resist the temptations of fame and fortune, and ultimately place the fishpond under collective management, ensuring that the spirit of safeguarding the pond and remaining true to one's principles is passed down through generations in their homeland.
