"A Hot-blooded Man") is a 2006 South Korean neo-noir crime drama film written and directed by Lee Jeong-beom.

The narrative centers around a small-time crook who partners with a retired taekwondo practitioner to seek revenge on the man who killed his mentor, and ends up befriending the killer's mother who reminds him of his hometown.

Although a physically imposing black belt in taekwondo, Chi-guk (Jo Han-sun) is a soft-spoken newcomer to gang life, who is quietly offended by Jae-mun's arbitrary and random acts of cruelty and rudeness against him and others.

Together, they travel to Dae-sik's hometown, a remote rural village called Bulgyo in South Jeolla Province.

While waiting for an opportunity to perform the hit, Jae-mun coincidentally befriends Dae-sik's mother Jeon-sim (Na Moon-hee) and spends some time with her.
