Plot
In a fictional Joseon dynasty, the royal palace is haunted by wongwi residing in a mirror dimension known as the Realm of Gwi. For thirty years, the royal line of succession is plagued by unexplained deaths among the heirs. The King hires Gu-cheon, a ghost-slayer capable of projecting his soul into the Realm of Gwi, to eliminate the entities targeting the palace. Gu-cheon works alongside Saeng-gang, a low-ranking court lady who can communicate with the dead. Saeng-gang is secretly the King's estranged daughter, seeking to investigate her mother's past murder.
Following the poisoning of the Crown Prince, palace rumors attribute the death to a vengeful Pond Spirit—the ghost of an executed court lady. Gu-cheon and Saeng-gang track the entity into the Realm of Gwi, where Gu-cheon destroys it. However, the deaths continue with the illness and demise of Prince Yeongan, the King's remaining heir. During their investigation, they are occasionally aided by Ggeomeoksali, a spirit bound to Gu-cheon.
Saeng-gang's investigation reveals that the supernatural curse was fabricated to mask human intrigue. Consort Sukbin, the King's mother and Saeng-gang's grandmother, had used the legend of the spirit to poison successive heirs to secure the King's ascension to the throne. Saeng-gang discovers her mother was murdered after assisting in these actions. Furthermore, the late Crown Prince had learned of the plot and assassinated his brothers to ensure his own succession, leading the King to secretly execute him.
Upon his death, the Crown Prince's lingering resentment turns him into an akgwi in the Realm of Gwi, where he spreads a fatal disease throughout the palace. To gain the power necessary to fight the spirit, Gu-cheon seeks out the primordial entity known as the Supreme Gwimae. During the final confrontation, the King confesses his remorse to his son's spirit, weakening the Crown Prince's form and allowing Gu-cheon to destroy him.
In the aftermath, Consort Sukbin is banished from the palace, the Queen Dowager retreats to her private residence having lost her sanity, Prince Ik-sang faces investigation regarding his use of shamans, and the King remains on the throne, tormented by visions of the victims of his family's political maneuvers. Gu-cheon and Saeng-gang depart the palace together. As they leave, Ggeomeoksali observes that a spectral chain remains attached to Gu-cheon's wrist, indicating his bond to the Realm of Gwi is permanent.
