Duel: Final Round (2016)

In the heart of a bustling city, Kang-Ho, a renowned police officer known for his bravery and tenacity, finds himself embroiled in a harrowing investigation following the discovery of a mutilated body floating in the river. As he delves deeper into the case, Kang-Ho's relentless pursuit of justice leads him to confront a dangerous suspect alone, a decision that proves to be his undoing. Despite his reputation, he underestimates the threat he faces, resulting in a brutal confrontation that leaves him gravely injured and in a coma, casting a shadow over his once-bright career.

While Kang-Ho lies unconscious, his younger brother Poo, a lesser-known officer with a chip on his shoulder, steps into the fray. Determined to uncover the truth behind his brother's attack and the murder, Poo grapples with feelings of inadequacy and the burden of living in Kang-Ho's shadow. As he navigates the treacherous underworld of crime and corruption, Poo discovers hidden strengths and allies he never knew he had. With each lead he follows, the stakes rise, and he realizes that the danger is more profound than he initially thought.

As the investigation unfolds, Poo must confront not only the criminals responsible for his brother's near-fatal injuries but also his own insecurities and fears. With time running out and the city on the brink of chaos, he races against the clock to bring the perpetrators to justice. The final round is not just a fight for Kang-Ho's life but also a battle for Poo's identity and redemption. In a world where courage and loyalty are tested, both brothers must rise to the occasion, proving that true bravery often comes from the most unexpected places.
