Never to Lose(2005)

Never to Lose is a South Korean crime film following the struggling detectives of Homicide Unit 3. Led by veteran Detective Koh and joined by eager rookie Detective Min-jun Kim, the unit battles incompetence and internal friction—including Detective Ryung, who fights for respect in a male-dominated squad. When Kim stumbles upon intel about a drug deal at a party, the team sees their chance for redemption. What begins as a promising case spirals into something far deadlier: a confrontation with Korea's most powerful drug lord. As ambition collides with survival, Homicide Unit 3 discovers they've become targets in a game they can't afford to lose.
