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.

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.
