Coincidentally, the cultural assets Skunk sends to the Cultural Heritage Team match the missing assets listed by Dae-myung a while back. Tae-in finds the connection rather suspicious and plans to use Dae-myung as bait to lure Skunk in. Meanwhile, the ambitious Kim Young-soo, the director of Mugung Art Gallery, puts up a national treasure for auction. And Dae-myung, who was put on a particular task by the Cultural Heritage Administration, heads to the auction.

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.
