Stealer: The Treasure Keeper - Season 1

Inspector Choi Min Woo transfers to the Cultural Heritage Team of Seoul Metropolitan Police Agency after getting into trouble with her superior at the substation. Instead of greeting her at the police station, Tae In, the team captain, calls her to the broadcasting station for her first mission. Meanwhile, Young Chan loses the goods he illegally smuggled to Skunk again, so he joins hands with Chairman Yang, who is looking for the Joseon Tongbo with holes. 

Skunk breaks into Choi Song-chul's house with the help of his assistant, Chun-ja, to steal Volume One of Jikji. However, high-voltage currents run across the rooftops and grounds at his house that can even take one's life once they make a single mistake. Meanwhile, Tae-in visits the crime scene at Chairman Yang's summer house in the middle of the night alone to find out about the killer.

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.

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.

Skunk and his team successfully steal the Joseon Tongbo coin at Jang Chun Fung's hotel according to the plan. However, Viper appears out of nowhere to ruin it as if he knows their location. Meanwhile, Young-soo desperately waits for the fated moment to come, and Ae-ri gets into Dae-myung's room at the hotel and finds Skunk's mask.

Team Karma safely returns from Jeju Island and looks into traps in Young-soo's secret vault in the training facility of Mugunghwa Foundation. However, they cannot get a signal to it even with the GPS tracker on the fake Joseon Tongbo coin. Meanwhile, Ae-ri joins Team Karma, and her first mission is to get Young-soo's fingerprint.

Skunk and Min-woo manage to get inside Young-soo's maze. However, it is their first time sneaking into a secret vault without any information, so they have to make sure they don't get caught in his traps. Meanwhile, Young-soo knew they were planning to break in all along, and he is waiting for them to fall for his deadly trap.

Dae-myung and Min-woo reach the last room out of the three traps. The third trap looks like an ordinary room but has a strange-looking clock in it. Meanwhile, Doctor Ko reappears to join Team Karma, and Min-woo gets shot by Young-soo.

Dae-myung gets furious when he realizes Viper is the murderer who killed his parents. Viper gets away, and Dae-myung faints when Tae-in and Chang-hoon arrive. Now that the day Kim Young-soo has been waiting for comes, he heads to Gyeongju, and Team Karma tracks him down.

Viper is on his way to take revenge on Young-soo. He finds out his sister was killed by Shota, and he has been fooled by Young-soo all along. Finally, the handle of the Big Dipper dips into the well as predicted, and Young-soo is about to get the Bead of Eternal Life in his hands.
