Don't wanna get dirty? Take off your jacket, you! Just let me go! Code name, 66. North Korean agent. This man looks like a complete loser. But the moment his daughter disappears, the monster he's been hiding for years finally wakes up. His name is Agent Kim, and to everyone else, he's just another invisible employee in a bank-sotted department. For years, he's kept his head down, believing that if he stayed quiet and never fought back, he could protect the only family he had left. He was wrong. His daughter, Min Jae, is constantly bullied at school because she comes from a single-parent family. After her classmates insult her late mother, she finally snaps and fights back. The girl she hits happens to be the daughter of one of the most powerful construction icons in the country. Against that kind of power, the truth means nothing. Agent Kim swallows his pride, apologizes, and even kneels in front of everyone, hoping it will be enough to keep his daughter safe. The next day is Min Jae I.S. birthday. Agent Kim buys her a cake, cooks her favorite dinner, and waits all night for her to come home. The following morning, he learned she was never at her friend's house. Someone used a fake message to lure her behind the school. Following the trail, Agent Kim discovers a pool of blood. Moments later, Higher Eye arrives with a group of thugs to clean up the scene, acting like nothing ever happened. Agent Kim silently opens his hand and shows them the hair tie. None of them realize they've just made the biggest mistake of their lives. Because this timid bank clerk isn't who he seems. He's Agent 66, a legendary rogue operative who once carried out some of the world's deadliest covert missions. And when a father stops pretending to be weak, everyone responsible for hurting his daughter is about to discover why he was once the man everyone feared.
