River Where the Moon Rises

In ancient China, Queen Yeon seeks a general's help to protect her people — but a power-hungry vassal plots against her, provoking the king's jealousy.

Eight years after losing her memory, Princess Pyeonggang becomes the assassin Ga-jin. Following a mission, she meets a carefree On Dal in the mountains.

Dal treats a wounded Ga-jin after a failed assassination attempt on the king. But when she returns to the Cheonjubang, she walks into a new predicament.

Yeom Deuk searches for Ga-jin, who is being held captive in a cave. Later, after revealing the truth of her past, he urges her to find her parents.

Regaining her memories, Ga-jin learns the truth about her mother's death and the tragedy that befell Dal's father. General Go tries to shield Ga-jin.

Dal tries to persuade Ga-jin to live in the Ghost Valley — but his world spins into chaos when he discovers her secret identity from Go Geon.

General Go informs the king that the princess is alive, while seeking to trick Go Won-pyo. Ga-jin seeks a new life in Ghost Valley.

Ga-jin and Dal dig a well for the village. King Pyeongwon orders Ga-jin's capture but Go Geon's protection leads to punishment.

To save Dal, Ga-jin returns to the palace as Princess Pyeonggang. But her arrival sparks tension when she confronts her father about the past.

A potential poisoning compels Ga-jin to inform the king. But when her warning is dismissed as delusion, she realizes there is trickery at play.
