The Auta tribal chief in death throes vows vengeance against Silla, and their blood and resentment fill the place where the Sacred Tree was standing, and turns into a lake.

Queen Jinseong (Kim Hye-ri), troubled by the threats to the throne, leans on General Biharang (Jung Joon-ho) against the counsels of her ministers.

He, however, spurns the Queen's romantic attentions in favor of his betrothed Jaunbi (Kim Hyo-jin), the daughter of an executed rebel, with whom he wishes to settle down and lead a quiet, peaceful life.

While Biharang has left for the country's border to quench the rebels, Jaunbi is chased by assassins who were ordered by the Minister Mun-su to kill her.

When the moon soaked with a thousand years' resentment shines its rays upon the dark earth, an age-old revenge begins, and love turns to tragedy.
