The Empress Ki

Brought as a royal tribute to the Yuan, Ki Yang of Goryeo flees with her mother. Yang spends her childhood masquerading as a boy named Seung-nyang.

Seung-nyang gets caught smuggling, and Goryeo gets a new leader. Crown Prince Ta-hwan is sent into exile. What is Yeoncheol plotting?

King Wang Yu hurries to Ta-hwan's encampment, where his Yuan counterparts devise a secret plan. With the Prince in danger, Seung-nyang must take action.

Seung-nyang and Ta-hwan grow closer, leaving Wang Yu conflicted. Yeoncheol takes action in the Yuan empire with Baekan.

Seung-nyang desperately tries to bring Ta-hwan to Wang Yu in order to save her father, who has been falsely accused of Ta-hwan's murder.

At the palace, Ta-hwan breaks a promise, leaving Seung-nyang suffering a terrible loss — and vowing revenge.

Dang Gise realizes Seung-nyang is a woman and begs her to become a concubine. Yeoncheol prepares for his daughter's wedding in the Yuan capital.

Yang takes up a position in the Yuan palace, inching closer to executing revenge. Wang Yu fights for command over the Goryeo armies.

Yang runs into Ta-hwan while assigned to look after a lady of the court. Meanwhile, Wang Yu thinks of a strategy to counter Baekan.

When a court lady becomes pregnant, Tanashilli and the Empress Dowager confront a distracted Ta-hwan. The battle worsens on the western frontier.
