The Emperor's Lost Gold
After a botched operation puts Hae-sung and his team in serious jeopardy, the only way for him to salvage his career at the NIS is to accept an assignment that seems almost hard to believe. Hae-sung and his team must infiltrate Byeongmun High School, one of Korea's most elite private institutions, to recover ten tons of gold bars worth a staggering 80 million dollars. With everything on the line, Hae-sung puts on a school uniform, and "Operation Undercover High School" begins.
Spooky Stories
Hae-sung comes dangerously close to blowing his cover while searching for the hidden gold in Byeongmun High School's eerie old building, barely escaping detection by Soo-ah, his sharp-eyed homeroom teacher. As he hears chilling rumors and faces tight security surrounding the building, he believes that's where he'll find the gold. While dealing with school bullies, Hae-sung begins plotting his next move to uncover the dark secrets lurking inside the old building.
Ghost Story Riddles
Hae-sung uncovers a crucial clue hidden within the old building, but Chairwoman Seo quickly learns its potential connection to the elusive gold bars. Sensing the connection, she keeps Hae-sung under close watch. Meanwhile, as Hae-sung delves deeper into the ghost stories surrounding the school, he finds himself caught in the escalating tension between Tae-soo and Dong-min, whose conflict ignites chaos throughout the school.
Joining the Student Council
Hae-sung attends the anti-bullying committee session with a key witness who clears his name, while Dong-min finally finds the courage to stand up for himself. With his name vindicated, Hae-sung uncovers the existence of another grandfather clock hidden in the student council room, and the only way to get closer to it is by joining the student council. With the help of his team, he tries to meet the strict requirements.
Student Council
Hae Seong and the team grow increasingly concerned that Su A's suspicions could threaten his undercover mission.

Meanwhile, a shadowy figure emerges, threatening to expose Hae Seong's true identity
Hye Seong's Father's Notebook
The school's security guard dies, leaving Hae Seong a notebook belonging to his missing father. The revelation is shocking, and he storms the NIS for answers.

The 24th Anniversary of Byeongmun High School

However, a missing key component forces Su A to join the mission despite Hae Seong's strong opposition to her involvement
The Plan for VIP Students
