The Great Queen Seondeok

Court Lady Mishil seduces the kings of Shilla to gain enormous power and influence over the royal court, but a prophecy regarding twins promises her eventual downfall.

King Jinpyeong and Lady Maya have twin daughters, forcing the king to send the younger daughter away with the maid Sohwa before Mishil can get her hands on the girl.

Fifteen years later, Deokman lives a life of a merchant with her mother Sohwa. King Jinpyeong's line of male heirs comes to an end.

Deokman displays her wits against a Chinese official. Lady Mishil's personal guard Chilsuk finally tracks down Deokman as the twin, and attempts to kill her and Sohwa.

After her husband's death, Princess Chunmyung leaves for the countryside to give birth to her son and keep him far from the reaches of Mishil.

Chunmyung encounters Deokman and mistakes her for a boy. Deokman believes Chunmyung is a nun and saves her life.

Saved by Princess Cheonmyeong, Deokman feels somewhat intimate with her. Yusin saves Princess Cheonmyeong.

Deokman is arrested and brought to the palace, but Chunmyung intervenes and assigns her to be part of the Hwarang.

Yusin and The Followers of Maitreya return from the battle, only to face disdain from The Ten Elite Hwarang.

Yusin is being called to be under the command of Seolwon while Deokman stays in Amagseong Fortress.

Deokman survives an attack, but for Silla to win, Yushin's battered troops are forced to face the enemy once again, alone.

The Hwarang are rewarded for their achievements in battle. Deokman is arrested under suspicion of trying to assassinate Yushin's father.

Deokman discovers Chunmyung's true identity. Mishil's background is revealed and the source of her power is suspected to arrive at the palace through a foreign trading delegation.

The Sadaham Plum Blossom turns out to be an almanac. As Deokman tries to spy on Mishil, she discovers the true fate of Chilsuk.

Mishil attempts to discredit Deokman in front of Yushin and Chunmyung, but is thwarted. Instead, Deokman manages to get close to Mishil and spy on her for Chunmyung.

Using the almanac to her advantage, Mishil makes a prediction to manipulate the royal court. She attempts to bring Yushin over to her side.

Through Mishil, Deokman is one step closer to finding out her true identity. She attempts to meet with the king to answer her questions.

A theft among the Hwarang nearly forces Deokman to reveal her true gender, but Chunmyung's own questions and investigations lead her to learning the truth.

Chunmyung tries to send Deokman far from the palace and away from Mishil. Though unable to meet with the king, Deokman pursues a meeting with Queen Maya.

Princess Cheonmyeong tells Queen Maya that Deokman is her lost twin sister. Deokman tries to sort things out.

Yushin and Deokman go on the run as everyone in the palace realizes who Deokman is. Bidam, Mishil's secret son, appears.

Deokman and Yusin sneak into Yangjigol Village. Mishil and Jinpyeong are at odds with each other.

Yushin, Deokman, and Bidam form an unlikely alliance against Mishil's soldiers. Chunmyung searches for Deokman with Alchun and other Hwarang guards.

Hwarang Daenambo is sent to kill Deokman, but a case of mistaken identity leads to the wrong person getting killed.

With the death of Chunmyung, Deokman plans to take revenge and earn her rightful place in the royal family.
