It's about the love affair between a whore who also does some sleezy cabaret dancing and whoring and some rich dude. The club she dances for is owned by some Turkish gangster who gives the rich dude a very hard time.

The scene you'd be interested in is with one of the chicks johns who complains that her ass stinks. She ensures him it doesn't and sticks a finger inside to smell, then of course let's him smell her finger to which, amazingly, he retracts the original statement.
