Netflix has unveiled the trailer for the upcoming supernatural series, The East Palace.

The official synopsis reads: “When the crown prince is found dead in a pond, a chilling rumor paralyzes the palace: the pond spirit has returned to wipe out the King’s bloodline. The King (Cho Seung-woo) fiercely dismisses the killings as mere conspiracy, until his last remaining son, Prince Yeongan, collapses.

“Driven to desperation, the King secretly summons Gu-cheon (Nam Joo-hyuk), who can traverse the Realm of Gwi and defeat them. To ensure his loyalty, the King pairs him with Saeng-gang (Roh Yoon-seo), a court lady born with the ability to hear spirits.

“Gu-cheon embarks on the life-or-death mission to destroy the spirit and lift the curse of the East Palace, or die within its walls. But as Gu-cheon hunts the spirit and Saeng-gang secretly spies on his every move, the two draw closer to the dark truth of the East Palace that lies beneath the pond.“
