While investigating a murder case related to Joseon Tongbo, Cultural Heritage Team finds out that someone is collecting all seven Joseon Tongbo. They could be the key to finding the assets lost during the Japanese Invasion of Korea. Cultural Heritage Team decides to dig this further and ask Dae-myung for cooperation.

Dae-myung joins the Cultural Heritage Team as Skunk to find the lost treasures of Joseon and get down on Mugunghwa Foundation. Tae-in starts their first project by questioning Kim Young-soo of Mugunghwa Foundation about Joseon Tongbo coins. Meanwhile, Min-woo successfully arrests Doctor Ko and takes off to meet an anonymous informant who knows about Chairman Yang's murder.

Skunk saves Min-woo from Viper and disappears again. Ironically, Doctor Ko joins Team Karma to search for the remaining Joseon Tongbo coins, and Dae-myung invites the team to meet Chun-ja for the first time. To get into Jang Chun Fung's safe, Team Karma flies to Jeju Island, but an uninvited guest tags along with Dae-myung.
