While he was eating a lot, Moo Gak received three text messages from Cho Rim. When he finally meets her and she proposes him to be her comedy partner he gets angry and sends her away. Moo Gak is busy solving a case in a week if he wants to become detective.

Cho Rim confesses that she knew from the smell. To be sure that she is telling the truth, Moo Gak left to hide and asked Cho Rim to wait 5 minutes and then to go and find him.
From the rooftop of a building Moo Gak is watching Cho Rim following precisely the path he took while he was hiding.
Moo Gak:” You really are like a dog.”
Moo Gak didn’t see her sniffing so he asks her. When Cho Rim told him that she can see scents he couldn’t believe her so he had to test her. Moo Gak has some candy from the restaurant he ate earlier so she covers her nose while he hides the candy. He is surprised that Cho Rim knew exactly where the candy is, even when he hid the candy in his own mouth.
Two people are missing. One of these people is fashion model Joo Ma Ri. The police officers believe that she was kidnapped by a serial killer. From few years now, once a year on the same date, people disappear and their dead bodies are found seven days later.
Moo Gak’s team is in charge of finding Joo Ma Ri. Together with one of his team mates Moo Gak went to the hospital Cho Rim took him few days earlier. Joo Ma Ri was the client of a doctor from that hospital. Later Moo Gak meets Cho Rim and together went to Joo Ma Ri’s house. They check out Ma Ri’s clothes and perfume for Cho Rim to see her scent.
Moo Gak:” We just need to smell some things and go.”
While walking with Moo Gak, Cho Rim sees a man with the same scent as Ma Ri. She tells Moo Gak and he attacks that man. He is Kwon Jae Hee, Ma Ri’s boyfriend.

While eating with a friend Cho Rim noticed that her friend has the same wallet that Ma Ri had and found out that the wallet shouldn’t have a leather smell because the producer is an animal activist. She calls Moo Gak and both of them went to search around the area where the wallet was found. They found out where Ma Ri’s body is.
