Yun Jin was once the emperor's favorite concubine, but she was demoted to the sidelines, but she detonated gunpowder on the night of the Ancestral Temple ceremony, burning away the royal family's centuries-old faith. The government and the public were in an uproar. No one knew that this useless concubine held secrets that could overthrow the dynasty. When Yu Chiye, the commander of the imperial army, was ordered to hunt her down, he recognized the birthmark on her neck that was exactly the same as her late mother's in the firelight - it turned out that she was not a sinner, but a true bloodline buried by the royal family. The two confront each other in the bloody dawn. One is an iron-blooded handsome man who is ordered to kill the rebels, and the other is a vengeful orphan girl who holds the secret. The past grudges and the current truth can only be revealed by life and death.
