Kim gladly devotes himself to a quiet life as a father and office worker, and the SMD leaves him alone. But when Min-ji goes missing and Kim starts wreaking havoc across the city looking for her, North Korean Intelligence learns of his continued existence. The SMD and North Korean Intelligence both set out to capture Agent Kim.
Who is Agent 66?
The pseudonym “Agent 66” is first used by Park Yeong-gwang (TaecYeon), a North Korean spy who trained alongside Agent Kim. When Yeong-gwang dies during his and Agent Kim’s first mission to South Korea, betrayed by the North Korean agency that sent them, Agent Kim takes on the moniker.
When Agent Kim reappears on the North Korean government’s radar after years of being presumed dead, Park Yeong-gwang’s little brother, Gang Seong (Kim Sung-kyu), is sent to kill him. He too uses the name “Agent 66” as his codename. Though killing Kim may be Gang Seong’s orders, the mission is also personal for the new Agent 66, who has been told that Kim is responsible for the death of his big brother. When Kim dispels this lie, revealing that it was North Korean intelligence director Ri Eung-ryeong who betrayed them all, Gang Seong abandons his mission to kill Kim.
