When the syndicate captures Detective Ma and attacks the squad, the film reveals the team's true background: each officer was recruited because they are elite combat specialists. Detective Ma is a former national judo champion, Detective Jang is an Asian Muay Thai champion, Detective Jae-hoon is a pain-immune former baseball slugger, Detective Young-ho is an ex-naval sniper, and Captain Go is an indestructible "Zombie" who has survived twelve stab wounds. In a sprawling harbor container battle, the five detectives single-handedly dismantle both syndicates, ultimately earning long-overdue mass promotions.
