The movie name starts with a "M" and has a "K" in it.
The only things I can remember is that a young Asian/Chinese/Japanese teen boy travels to a place and meets this girl he likes, but ends up messing around with a girl that two American men want to prostitute but the boy tries to help her.
They capture her and take her to a club where the boy follows them and ends up fighting with the people in the club. He meets the two American guys but gets beat up. He goes to their hotel (I think) and starts to find them but he ends up following them to a truck port where he finds more girls have been prostituted and fights the two Americans at the same time.
He sees the girl but knows that she isn't a virgin any more because one of the Americans raped her. That's all I can remember. Please help me find this movie.
