Chen An returns to his hometown for his grandfather's funeral, only to discover that Zhang Fugui has sealed off his home with a brick wall and seized his family's ancestral fishpond, turning it into a fishing resort. Keeping his anger in check, Chen An holds two trump cards left to him by his grandfather and carefully puts his plans into action. He diverts underground river water to cut off the Zhang family's fishpond income, rallies villagers to submit joint evidence, attracts investors to develop a hot spring resort, and even reveals the main hot spring vein in front of everyone at a village meeting. After successfully securing legal ownership of the land, Zhang Fugui finally comes to his senses and personally tears down the brick wall blocking Chen An's entrance. Chen An builds the Peaceful Hot Spring Resort, allowing the whole village to share in the benefits of development. This is a battle to reclaim rural land, win back justice, and regain the people's trust.
