Kwon Bob: Chinatown (2015)

Description:

Chinatown is a place where crime and betrayal are rampant. Violent crime detective Ko Jeong-hyeok (Seo Joon-yeong) can't rest a day. He tries to rid the streets of criminals but he's to busy cleaning up his own mess because of his habit of using physical violence first. Lately, he's been so desperate to capture Song, the boss of an organization that deals with smuggling drugs and human trafficking, that he ignores his girlfriend Ji-hyeon's (Ban So-yeong) request. Ji-hyeon does voluntary work for homeless people but one day notices that one or two of them have gone missing. She'd asked Jeong-hyeok to help her find them but he only has Song on his mind. Then one day, a source tells Jeong-hyeok about the location of Song; however, he fails every time to capture him because of interference from Black Society, one of the biggest Chinese gangs. It turns out the boss of Black Society and his gang were also after Song who had brought harm to their organization. Tension rises between Jeong-hyeok and Black Society who are both out to get Song. Jeong-hyeok has nothing but guts although he fights the gang who are also the best martial arts fighters in China.
