What happens in Officer Black Belt?

Happy-go-lucky Jeong-do (Kim Woo-bin) is a fried chicken delivery guy who loves to game nonstop. He also knows how to fight: He holds third-degree black belts in tae kwon do, judo, and kendo — making him a ninth-degree martial artist. In any and every sparring match, Jeong-do crushes his opponents with ease. One day while coming home from work, he witnesses someone wearing an ankle monitor brawling with a police officer. Jeong-do steps in, using his expert martial arts skills to subdue the attacker. Impressed, the officer introduces Jeong-do to his co-workers at the police department, inviting him to sub in while he recuperates from his injuries. And so, Jeong-do becomes a martial arts officer, fighting crime alongside his new sidekick, probation officer Seon-min (Kim Sung-kyun). As he seeks justice, Jeong-do also learns a thing or two about himself and what makes him happy.
