Film: Slumming

What can I say to describe this movie?

A guy, well two guys who try to play God once in a while in the "slums" of Austria. The main one actually falls in love (I guess) and realizes what life is all about... in Indonesia (?).

She - the girlfriend - tries to save a homeless guy that does not need saving (?)

And that's it. I liked it. Don't know why, but liked it.
