 Each of the four vignettes that make up "People in Cages" addresses different social issues, such as racism, and how people can become trapped by society.Although some of these issues are weighty, and each play is ultimately quite tragic, the plays themselves are laced with humour and comedy.The humour is typically very surreal in view of the unusual premise of having people locked inside cages for the viewing pleasure of others and that some of these people are out of the ordinary in unexpected ways.
