A retro office comedy depicting the chaotic events that unfold in the late 1990s when Sammo Hung, a 30-year-old elite securities supervisor who only cares about work, goes undercover as a 20-year-old high school graduate employee at a securities firm where suspicious money flows are detected.
While investigating Hanmin Investment & Securities, Hong Geum Bo faces a setback after meeting an informant — forcing her to go undercover.
Disguised as a 20-year-old employee, Geum Bo cozies up to Ko Bok Hui for intel — until her heart skips a beat when Sin Jeong U arrives at work.
While avoiding Jung-woo, Keum-bo continues investigating leads undercover. Meanwhile, she clashes with Bok-hee - causing tension at home.
Despite preventing a disaster at work, Keum-bo faces imminent termination. While trying to secure her employment, she tries to track down "yehppee."
A new arrival at the residence bothers Keum-bo. After learning of a spy, Chairman Kang orders an internal hunt — pushing Keum-bo to find "yehppee" first.
To get closer to the truth about the slush fund, Keum-bo tries hard to win the top employee contest. Later, Jung-woo confronts her in a stuck elevator.
