Only then does she learn that a Mongolian princess's marriage to a Han general was no heartwarming tale of harmony between Mongols and Han, but a tragedy in which the princess was buried alive as a sacrifice. After enduring six cycles of reincarnation, she returns from ancient times to the modern era and happens upon her lover from a past life. They rekindle their romance, but meet too late, and their story ends in a double suicide, becoming an eternal love that echoes through the ages.
