Cinema VinesThe South Korean spy‑thriller “Agent Kim Reactivated,” starring So Ji Sub as Kim Do Hyeon, wrapped up its 10‑episode run on July 25, 2026, after becoming the highest‑rated Korean drama of the year with a peak nationwide rating of 23.1%. The series was broadcast on SBS and streamed worldwide on Netflix, cementing its place as one of the biggest television hits of 2026.
So Ji Sub returned to the small screen after a multi‑year hiatus, and within the first four episodes the show shattered real‑time viewership records, drawing widespread attention. The plot centers on Kim Do Hyeon, a quiet bank manager and devoted single father who once served as the legendary black‑ops operative Agent 66. When his teenage daughter, Kim Min Ji, is kidnapped by a criminal syndicate linked to powerful businessman Ju Gang Chan, Do Hyeon is forced to abandon his peaceful life and re‑enter the world of espionage.
Do Hyeon reunites with former teammates Seong Han Su (played by Choi Dae Hoon) and Park Jin Cheol (Yoon Kyung Ho). Together, the trio mounts a daring rescue mission to save their children while dismantling Gang Chan’s criminal empire. The climax sees the three fathers face a brutal showdown: Gang Chan threatens the children of Han Su and Jin Cheol, forcing them to choose between killing Do Hyeon or losing their kids. The fathers appear to betray Do Hyeon, but the attack is a calculated ruse that weakens the villain’s defenses.
In a dramatic turn, Jin Cheol delivers a decisive kick that breaks the cage, trapping Gang Chan. The trio then overpowers the businessman, leaving him dangling from the rooftop of his own company, symbolizing the collapse of his empire. Shortly thereafter, Ju Hak Constructions is dismantled and Gang Chan meets his demise in broad daylight at the hands of Golden Teeth, a betrayer he had previously wronged.
The finale’s twists—particularly the reveal that Do Hyeon is Agent 66—have sparked speculation about a potential second season. With its blend of high‑speed spy action and a heartfelt father‑daughter narrative, “Agent Kim Reactivated” has left audiences eager for what comes next.
