Hong Ji Ah (Jang Na Ra) is a powerful exorcist and the owner of Daebak Realty, a company specializing in selling haunted houses after clearing them of their resident ghosts. Her method involves physically driving out the spirits by touching a specific object connected to their death, but she needs a psychic medium to facilitate the process. Enter Oh In Bum (Jung Yong Hwa), a con artist who pretends to be an exorcist by using his sharp observational skills to trick people into believing he can see ghosts. However, after an exorcism unlocks In Bum’s previously-unknown psychic abilities, Ji Ah reluctantly enlists his help. As they work together to cleanse various haunted properties, they uncover deeper mysteries surrounding their own pasts, including the truth behind Ji Ah's mother's death and In Bum's family history, realizing their destinies are far more intertwined than they ever imagined.
