Mi Soon and Ye-Eun got cornered by the Chinese mafioso Wang Kai. They abducted them inside his suite room. He instructed them to summon Chan Min to join them.
Mi Soon contacted Chan Mi. She asked her to get inside the room, or else Wang Kai will shoot them. They never knew that Chan Mi held one of his men, by letting him wear a bomb vest. Chan Mi met Wang Kai and threatened him to pull the trigger if he doesn't release Mi Soon and Ye-Eun.
Wang Kai agreed to her requests. He unstructured his men to put all their guns down. Team leader Dong arrived with NIS back up team. They arrested Wang Kai and his men. Mi Soon and Ye-Eun were amazed by what Chan Mi did. But Chan Mi revealed that it's a fake bomb just for their mission.
The good casting agents urged Wang Kai to contact Ok Chul, alias Michael. They instructed him to inform Ok Chul to proceed to the hotel. But Wang Kai gave Ok Chul a signal to escape. Chan Mi and the rest of the team are desperate to track Ok Chul's phone line.
Seok Ho contacted Chan Mi and informed her that Mr. Byun went to Jeju island. He is after for Michael too and got inside contacts from the white-collar. Seok Ho is on his way to the island as well.
Mr. Byun met Ok Chul at an abandoned school. They brawled for the tech chip and tried to kill each other. Mr. Byun overpowered Ok Chul and took the chip from him, but Ok Chul stabbed and shot Mr. Byun, leaving him to the ground half-conscious. Ok Chul ran to the ground and took his car to flee.
Chan Mi asked the head office to track Mr. Byun's phone via satellite. They found him in a location near her. As she parked her car, she heard the shots and found Mr. Byun lying on the ground. She went after for Ok Chul as Byun insisted.
Chan Mi was standing at the center of the school ground, targetting Ok Chul's head. One shot from Chan Mi and the second one from Dong resulted in Ok Chul's arrest. At the same time, Byun died in Seok Ho's arm as he arrived a few minutes after.
Back in Seoul, Director Myeong was sent to prison for fraud, leaking of technology, and corruption. Hwa Ran stepped down from her position and returned to Seok Ho the CEO position of Kwang HITECH. Kang Woo Won sued individuals who spread malicious rumors about him as he suffered from anxiety.
Kang Woo Won found out that Ye-Eun had a daughter, so she preferred not to get into any romantic relationship. But Kang Woo Won insisted he cares for her and loves Ye-Eun.
Chan Mi resigned as the CEO secretary. Seok Ho informed that he will invite her often since she is not undercover at his company. At the same time, Mi Soon made peace with her husband and promised that they will be a family as always.
Ok Chul planned an escape by slashing his wrist. He managed to walk inside the wardroom, but he got killed by an agent from the white-collar mafia.
Another mission is set up with Mr. Dong as the new NIS Chief to get inside the white-collar operation. He formed the same team - it's Chan Mi, Mi Soon, and Ye-Eun. They believe that their mission is successful due to good casting.
