Ten-year-old math prodigy Lin Xiaoman is sent to her grandfather's rural farm from Beijing due to her parents' job transfer. What she sees as a "miserable exile" quickly turns into a mission when she discovers the 30-year-old organic farm is being lowballed by a real estate developer using contract loopholes. Using her Olympiad math skills to expose the traps, Xiaoman teams up with village kids to promote the farm's "nature classroom" via short videos and helps grandpa design a "rice-shrimp co-culture" model. But the developer strikes back—they sabotage the shrimp fry, and Xiaoman stakes out for three days to catch them red-handed, filming evidence with a drone. When grandpa holds the winning judgment in tears, Xiaoman realizes: the "quest" is never about conquering—it's about protecting what the ones you love hold dear.
