Agent Kim Reactivated

So Ji-sub returns to television in Agent Kim Reactivated, a pulse-pounding action drama that aired on SBS in the summer of 2026. The series, created by Nam Dae-joong, follows a quiet single father whose past as a black-ops agent comes roaring back when his daughter vanishes. Ji-sub plays Manager Kim, a man who has buried his lethal skills under a mundane life, only to find himself forced to unleash them again. The cast includes Choi Dae-hoon as the relentless detective Seong Han-su, Yoon Kyung-ho as Park Jin-cheol, a shadowy figure from Kim's past, and Son Na-eun as Sang-ah, a resourceful ally. With 10 episodes spread across two nights, June 26 and 27, the show packs its spy-thriller punch into a tight, binge-ready format. The tone is gritty yet charged with dark humor, earning a solid 8.2 rating from early viewers. It's a tight, kinetic ride that balances family drama with bone-crunching action. [edit]

Kim Do-hyeon has spent fifteen years as Mr. Kim, a bank manager whose stooped shoulders, thick glasses, and reflexive apologies make him the most forgettable man in Seoul. He is a single father to Min-ji, a headstrong teenager who inherited none of his meekness. When Min-ji disappears after confronting school bullies tied to construction magnate Joo Kang-chan, Kim's carefully constructed facade crumbles. He is forced to reactivate the skills of a former North Korean black-ops agent, a life he abandoned on the day his daughter was born.

The series moves between two timelines. In the present, Kim wages a brutal campaign through Seoul's criminal underworld to find Min-ji. In flashbacks, viewers learn of his defection, the death of his wife, and the promise he made to her to leave violence behind. He is not alone. Seong Han-su, a former secret agent and taekwondo gold medalist who runs a children's martial arts dojang, and Park Jin-cheol, a former elite combat veteran now working as a crossing guard, are drawn back into the fight. These three men, who once killed for a living, reunite annually to drink soju and complain about teenagers, but now their reunion is a matter of life and death.

The antagonists form a layered web of corruption. Joo Kang-chan built his construction empire through violence and usurpation. Kang Seong, a North Korean operative whose brother Kim killed during his defection, arrives in Seoul with orders to eliminate him. The Golden Teeth Gang, led by a fixer named Golden Teeth, provides the criminal muscle. Each episode peels back another layer of Kim's past while advancing the desperate search for Min-ji in the present.[edit]
