Undercover (KR)

JTBC’s 2021 adaptation of the BBC original, Undercover, solidified its place in the Korean thriller landscape by blending high-stakes political intrigue with the intimate complexities of domestic life. Starring veteran actors Ji Jin-hee and Kim Hyun-joo, the series explored the heavy burden of long-held secrets. The narrative centered on Han Jung-hyeon, a former intelligence agent who spent decades living under a false identity to protect his family. When his wife, a principled human rights lawyer, ascended to a position of immense power, his past began to collide with their present reality. By focusing on the emotional toll of deception rather than just action sequences, the show resonated with audiences seeking depth. It remains a significant example of how international formats can be successfully localized while maintaining a distinct Korean social commentary.
