A Chinese illegal immigrant (Robert) who is seriously worried about survival and staying on in America - like all immigrants including legal ones like myself.
An American woman (Claire) for whom life is about self-fulfillment including a casual romance.
When these two worlds meet, grapple and try to come to terms, it comes apart.
The Chinese man works as a waiter in a restaurant and there are true vignettes of Chinese restaurant life.
Unwittingly perhaps, the director let on that many Chinese are not very truthful or in their culture it is not valued highly. When Robert (our hero) decides to come clean and honestly tell Claire what he wants, she doesn't recognize it because of the white lies he has told before.
Unfortunately the reviewers at amazon are unable to appreciate the subtleness and some sadness - much like real life. They are like Claire in the movie.
Great movie - could replace Chinese with Indian, Hispanic etc and would in many places still be accurate.
