Ho Doo (Kim Hyun Mok) and Ye Ji (Han Seung Yeon), struggling childhood friends, find themselves in a bizarre situation when Ho Doo rents an incredibly cheap house using Ye Ji's money. Initially excited about their new home, they soon discover something is terribly wrong when strange occurrences begin—flickering lights and an unusual smell—leading them to encounter a ghost. Unable to afford a professional exorcist, they attempt to banish the spirit using internet advice, which predictably fails. Their last hope becomes Ki Doo (Hong Seung Bum), an exorcist offering budget-friendly ghost-busting services. This is a 2021 South Korean supernatural comedy directed by Kim Eun Kyung.

There have been many court-related dramas, but there have never been any dramas based on the court itself. There have been many characters who took the roles of judges, prosecutors, and lawyers. However, rarely were their lives at the court depicted in detail. This drama focuses on the true nature of the court and the cutthroat competition among the judges as well as the conflicts, joy, sorrow, desires, and failures that they experience. Lee Jung Joo, also known as Judge Knucklehead, is a young judge who has lost both of her parents and whose older brother is incarcerated for the rape and murder of an underage girl. Sah Eui Hyun is a judge who strives to be fair, wise, and passionate in his field. Do Han Joon is a prosecutor who is also known as the Knucklehead Prosecutor. He is determined to sit his own father in court no matter what it takes.
