Lucy, a modern agronomy student, unexpectedly transmigrates into 18th-century America, inhabiting the body of an overweight, bullied young woman on a farm. Drawing on her agricultural expertise and cooking skills, she gradually revives the run-down homestead. She also rescues Jack, a fallen prince gravely injured and suffering from amnesia. As time passes, the two fall in love and grow side by side. Lucy expands her business from the farm and small town all the way to the kingdom. With Lucy by his side, Jack uncovers the poisoned schemes of the Queen Dowager and reclaims what rightfully belongs to him. In the end, irrefutable evidence condemns the Queen Dowager and her faction. Jack ascends the throne as king, Lucy becomes his queen, and their family is reunited for a satisfying happy ending.
