A modern woman accidentally receives a jade pendant at a delivery station and is transported to ancient times—along with the entire warehouse of packages. Mistaken for a murdered noble's daughter, she is married to a sickly prince. Using modern goods from her warehouse, she helps him fight political enemies and foreign invaders. When they are hunted, they discover a secret cave filled with modern weapons, and the prince reveals he too is a time traveler. Together, they lead a final battle to defend their kingdom.
