No Mercy for the Rude (2006)

The shoot-'em-up No Mercy for the Rude (2006) chronicles the slam-bang doings of severely speech-impaired hitman Killa (Ha-kyun Shin), who vows to only bump off targets who prove to be impolite. When he makes enough money from all this murder-for-hire, Killa plans to pay for an operation that will restore his voice. Wild action erupts end to end, pausing only when Killa romances a bar girl named She (Ji-hye Yun) who bares her North and South Korean knockers. Have Mercy!
