Set in the late 1990s, "Undercover Miss Hong" introduces Hong Geum Bo, an elite supervisor for the Financial Supervisory Service in her thirties, known for her coolheaded, job-focused approach. She embarks on a crucial mission, going undercover as a twenty-year-old high school graduate named Hong Jang Mi, to infiltrate a securities company where suspicious fund flows have been detected.
During her investigation, she meets Sin Jeong U, the ambitious new CEO of Hanmin Securities. A natural-born management consultant and corporate raider, Sin Jeong U trusts only numbers and will use any means to achieve his goals. Their professional entanglement takes a deeply personal turn when he recognizes Hong Jang Mi's face, identical to Hong Geum Bo, a woman he once loved. Their paths become complicatedly intertwined as the investigation uncovers more than just financial secrets.
