Mis-marketed as a gangster action movie, reviewers called it an intense family drama about motherhood, as a strong, self-sacrificing mother has no choice but to endure the hardships of having a hoodlum son.
A mob hitter, Jae-mun (Sol Kyung-gu) is the seasoned veteran of a mob family. He decides to go after rival mobster Dae-sik, the man who killed his boss and childhood friend a few years earlier. He takes Chi-guk with him as his partner in the assassination. 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. She comes to lovingly treat him as another son, and Jae-mun begins to feel conflicted. A tragic plot develops, culminating in a bloody showdown between Jae-mun and Dae-sik.
