Action Comedy Crime
Once a celebrated detective in the regional crime unit, Jae-hyuk lost his marriage, missed every promotion, and now lives as a washed-up small-town officer with a life in shambles. He’s paired with Jung-ho, a rookie detective and former social media influencer who brings sharp instincts, ambition, money, and youth to the table. This odd couple couldn’t clash more—until they arrest a thief stealing from a church donation box and discover he’s the prime suspect in a Gangnam murder case. The only problem? That case was already closed with a different suspect behind bars. Determined to catch the real culprit, the duo takes a work trip to Seoul. With prosecutor Mi-ju backing their investigation, they seek help from Gangnam Police Station. But their shaky partnership—more like team-killing than teamwork—threatens to unravel the entire case.
