Boarding Gate - Trailer

The description is probably more entertaining than the movie.

Boarding Gate

Asia Argento plays sexy ex-prostitute Sandra, who is forced to flee London after a steamy S&M encounter with a debt ridden ex-lover (Michael Madsen) ends in violence. Fleeing to Hong Kong in search of a fresh start, she becomes involved with an attractive young couple, Lester (Carl Ng) and Sue (Kelly Lin), who promise to help her obtain papers and money. But nothing turns out as expected for Sandra, and she finds herself trapped in a sordid game of manipulation.
