Sun Woong, a prosecutor at the Jinyeong Branch in the southernmost of Korea introduces his workplace. The case he's working on now is a dispute between a shaman and his customer. They believe he didn't perform exorcism after being paid, but the shaman himself disagrees. He's performed in at least 21 times. As the investigation carries on, Sun Woong does recognize the shaman's abilities. But something doesn't seem right.

Jung Woo gets to work with Myung Ju. On his first day in Myung Ju's office, an old lady wearing shabby clothes comes to the office. He falls for the old lady's act, and that's when Myung Ju shows up to set things right. Meanwhile, Jong Hak is heavily stressed out from work and pressured by his colleagues and supervisor, and he ends up falling ill and being taken to the hospital.
