Undercover Ms. Hong is set in the 1990s, shortly before the 1997 financial crisis. It follows Hong Geum-bo, a 35-year-old stock-market surveillance expert, who poses as a young high-school graduate at a Yeouido financial firm to investigate suspicious capital movements undercover. The lead role will go to Park Shin-hye, who will play a brilliant, independent but lonely woman.

Hong Geum-bo (Park Shin-hye), an elite financial investigator forced to pose as a 20-year-old rookie after uncovering suspicious financial flows. Under the identity of Hong Jang-mi, She moves into room 301, which she shares with Go Bok-hee (Ha Yun-kyung).

An ex-boyfriend and an unpredictable heir: the mission turns into a nightmare.

The first is Shin Jung-woo (Ko Kyung-pyo), the new CEO of Hanmin Securities... and Geum-bo's ex-boyfriend. Fifteen years earlier, they had been in an innocent relationship before Geum-bo abruptly ended it, calling him a «pathetic coward». Their sudden reunion plunges the heroine into a state of panic, forcing her to hide her face so as not to be recognized.

The second unexpected event is called Albert Oh (Cho Han-gyeol), a third-generation chaebol heir who joined the company at his grandfather's request. Their first encounter had been disastrous: an awkward altercation in a video store had left Geum-bo with a terrible impression, to the point of considering him a «pervert». Seeing him reappear as a parachuted-in department head only makes his situation worse.

A secretary with flamboyant style and clear dreams

Ha Yun-kyung lends her features to Go Bok-hee, the devoted personal secretary to the CEO of Hanmin Securities. In the rather dull world of Yeouido at that time, she immediately stood out with her flashy style, particularly her bright polka dot dresses. Ambitious but deeply endearing, Go Bok-hee has a natural charm that makes her hard to dislike.

Her goal is clear: to make a fortune and live freely, like a «California girl.» However, her carefully constructed dream begins to falter when she meets her new roommate, Hong Jang-mi, the undercover identity of Hong Geum-bo.
