When the village decides to spray pesticides to save its rice crops, Shen Qinghe insists on stopping them, warning that the young shrimp will die. Using her 50-acre experimental fields, she attracts insects with solar-powered pest-control lamps to feed the shrimp. As a result, rice grown in pesticide-treated fields exceeds residue limits and nobody will buy it, while her pesticide-free freshwater shrimp fetch an astonishing 80 yuan per pound. When powerful interests cut off her water supply, block her vehicles, and send diseased shrimp fry, she counters every move and uncovers their shady dealings. From being mocked as a troublemaker to getting the entire village to invest alongside her, her eco-friendly farming methods transform a poor village.
