Liu Jin, a PhD from an agricultural sciences academy, transmigrates to an impoverished ancient village just as a once-in-a-century severe winter strikes. She can barely survive alongside her frail, chronically ill mother, Liu Qing. Relying on her agricultural expertise, she builds a greenhouse in the depths of winter and grows fresh vegetables that no one has ever seen before. To obtain medicine for her mother, she risks entering the mountains to gather medicinal herbs and happens to rescue an injured young nobleman who has fallen on hard times. Her greenhouse vegetables quickly become famous throughout the county, attracting the attention of the Zhao family at the provincial governor's residence. They set their sights on her cultivation techniques and repeatedly make trouble for her.
