Royal Secret Agent (Season 1)

"Royal Secret Agent" (2020) is a Korean historical detective comedy you can watch online on iFILM. During the Joseon Dynasty, the king dispatched covert inspectors into the provinces with no badge, no escort, and no official identity. Their job: listen to ordinary people and expose local officials who extort and abuse their authority.

Kim Myung-soo leads the cast as the undercover inspector who reinvents himself for each new assignment. Corrupt magistrates, reluctant informants, and allies who may be playing both sides — every case is a fresh puzzle with real consequences underneath the light-touch framing.

A historical drama that moves more like an adventure than a period piece. Watch "Royal Secret Agent" (2020) online on iFILM.
