The Unwelcome Guest plot
One evening, a strange man comes to Guk-Seo's (Kang Shin-Il) home. The man's name is Tae-Ho (Park Joo-Hyung). He was involved in a club murder case seven years ago. Guk-Seo was a detective who investigated the case. Tae-Ho walks around Guk-Seok's house like he is in his own house. Guk-Seo looks at him without saying anything. Guk-Seo's daughter Young-Hee (Uhm Hyun Kyung) then appears. When they have dinner together, they begin to think about what happened seven years ago. The person who talks first becomes a failure.
