Four very different people are sent to take a class for their individual jobs. While waiting for the professor to arrive, they pass the time getting to know one another. But they're not really learning anything about each other. They're all harboring stereotypical views of each other that inevitably creep into their discourse to create an uncomfortable and often hostile environment in the small room. Their ideas about one another's ethnic and cultural backgrounds strain their conversation and encourage the viewer to think about their own views about ethnic differences and the stereotypes that drive wedges between people unlike anything else.
