Su Ye, the daughter of a convicted official, is exiled to the desolate province of Huangzhou. She voluntarily chooses Yan Xiao, a wounded and retired soldier, as her partner in surviving the harsh conditions. Armed with advanced agricultural knowledge, she improves farming techniques, transforms saline-alkali soil, and cultivates high-yield crops, leading villagers in scientifically reclaiming wasteland. When unscrupulous merchants collude with corrupt officials to drive up grain prices and deliberately sabotage their efforts, Su Ye uses the law and her intelligence to overcome the crises. She also develops drought-resistant crops to supply the frontier troops. Together, she and Yan Xiao work to protect the people and defend the border, building a prosperous and peaceful new future in the northern frontier.
