Mme Ma, Némésis

At National Forensic Hospital, an inmate, a woman who is known to have killed her own daughter, has gone missing. However, all the staff members at the hospital claim that they have thoroughly checked the number of inmates and that they have absolutely no idea where and when she has gone missing. Detective Han Tae Gyu is put in charge of investigating the situation and gets into a dispute with Ms. Kang.

The police go to Ms. Ma\u2019s house and make her husband, Jang Cheol Min, call her in order to trace her location. While talking on the phone, Cheol Min warns her not to come home just before getting subdued by the cops. Meanwhile, Ms. Ma visits the charnel house to see her late daughter, Min Seo.

During a flashback while Ms. Ma is being interrogated by Tae Gyu and Prosecutor Yang, she claims that although she had wanted to keep her daughter by her side, she did not kill her. In addition, she claims that a long-haired woman in a white hanbok has told her that she saw the killer. However, the police think that the long-haired woman is just a ghost and do not believe her.

The inmate that has run away from the hospital now lives at Rainbow Village while being disguised as a mystery novel writer, Ma Ji Won. One day, she tells one of her neighbors that her husband has a mistress. Three of the ladies gather together and go find the woman who is having the affair.

Thanks to Eun Ji\u2019s help, Ji Won scrapes through the situation where she could get caught by the detective Tae Gyu in front of her neighbors. However, she still doesn\u2019t know who Eun Ji is and why she offers help. After the ruckus, the residences in Rainbow Village start to get blackmailed. Meanwhile, a young boy called Woo Joon comes to visit Ji Won and asks about a bag.

Eun Ji finds out that Ji Won is looking for Actress Lee Jung Hee and says she\u2019ll help find the actress. They get to find some photos online that seem to be taken in Rainbow Village and follow where those photos lead. They end up in an empty house and find a man dead. In a doubt that the dead man has something to do with Lee Jung Hee, Ji Won visits her to ask about him.
