Anthony Campbell threatens to send his daughter, Marie, to China as punishment for her continued extravagance. She welcomes the suggestion because her sweetheart, George Holt, is planning a business trip to the Orient. When they arrive, Marie's Chinese maid, Liu Po-Yat, gives her a tiny vase to keep her from harm. However, the vase was stolen years earlier from the Manchus, China's ruling dynasty, and their pursuit of the lost treasure plunges Marie and George into danger.
