Known as an enthusiastic and impressively effective detective, Jin Kang-ho (Cha Tae-hyun) will stop at nothing to catch criminals he’s assigned to pursue. With the passion to solve the unsolvable cases, Kang-ho finds it’s better to work alone. Or so it was, until the day he meet Kang Moo-young (Lee Sun-bin), the overly zealous producer of a low-rated investigative program. Moo-young is as enthusiastic about solving cases and catching criminals as Kang-ho. The two then agree to team up and work together.
