2. Detailed Plot: “There has never been an investigation like this before”

The narrative led by Extreme Job Director Lee Byeong-heon and stars Ryu Seung-ryong, Lee Hanee, Jin Seon-kyu, and Lee Dong-hwi is a relentless sequence of laughter and tension. Let’s track the flow of the story in detail.

2-1. A Narcotics Team in Crisis and the Fateful Undercover Business

Captain Ko (Ryu Seung-ryong) of the narcotics team is pressured to disband the team due to a poor performance record. Trailing behind his juniors in promotions, he begins a stakeout near the hideout of South Korea’s largest drug cartel with his team members: Detective Jang (Lee Hanee), Detective Ma (Jin Seon-kyu), Young-ho (Lee Dong-hwi), and Jae-hoon (Gong Myung).

To maintain 24-hour surveillance, the team takes over the chicken restaurant directly across from the cartel’s hideout. However, the restaurant starts selling more chicken than they can surveil. Thanks to Detective Ma’s hidden cooking talent, the “Suwon Rib-Marinated Chicken” becomes a nationwide sensation as a must-eat delicacy.

2-2. Chicken Slayers by Day, Detectives by Night

The restaurant is flooded with customers, and the detectives find themselves busy butchering chickens and serving tables instead of catching criminals. Captain Ko suffers an identity crisis while looking at the massive sales figures, and Young-ho, the only one trying to focus on their original mission, is frustrated by the lack of cooperation from his team.

Meanwhile, evidence of a drug trade between the cartel leader Lee Mu-bae (Shin Ha-kyun) and his rival Ted Chang (Oh Jung-se) is detected. Although the team is nearly used as a money-laundering channel when they receive a franchise offer, they turn the tables and plan to infiltrate the heart of the organization.

2-3. The Twist of Identity and the Satisfying Takedown

In the final act, the true identities of the five members—who seemed completely absorbed in the chicken business—are revealed. Captain Ko is a veteran known as a “zombie” for his survival skills, Detective Jang was a national judo athlete, Detective Ma was a former wrestler, Jae-hoon was a baseball star, and Young-ho was an elite special forces operative.

They raid a massive drug deal at a pier, unleashing the overwhelming combat skills they had kept hidden. Director Lee Byeong-heon’s rhythmic action direction, combined with the actors’ dedicated performances, delivers the ultimate catharsis to the audience as the film concludes.
