It’s about estate agents who exorcise and cleanse buildings of ghosts and the people who died there. Hong Ji Ah (Jang Na Ra) is the head of the exorcists at Daebak Real Estate. Although she seems perfect with her beauty and intelligence, she is actually a hot-tempered exorcist whose fists come before her words. Her ability to exorcise has been passed down from her mother. Oh In Bum (Jung Yong Hwa) is a con artist who doesn’t believe in ghosts but uses them to make money. He has the perfect skills for a con artist, being able to use his keen powers of observation and reasoning to determine causes and effects, as well as to predict future outcomes for any situation. Hong Ji Ah will team up with Oh In Bum to uncover the secret behind her mother’s death 20 years ago.
