My Wife Is a Gangster 3 (2006) on Netflix

Plot summary

Han Ki-chul's Big Boss puts him in charge of looking after Lim Aryong, who arrives from Hong Kong. The crew braces for a big male gangster and instead meets a woman who keeps her distance and answers them coldly. Nobody on either side speaks the other's language, so Yeon-hee is brought in to translate. She is immature and frightened of the gangsters, and rather than pass on Aryong's rude answers she replaces them with pleasant ones. Aryong needs no protection in a fight: she beats other bosses to pull her companions out of trouble, and the men, unskilled themselves, come to fear her. When she tries to be friendlier, Yeon-hee undoes the effort by turning her words into threats.
