What is the main conflict in The Shadow Box by Michael Cristofer?

The work interweaves the lives of three dramatically different terminally ill patients and their loved ones to give a dynamic, well-rounded perspective of death and dying. The richness of the play is exemplified by its unity. The action takes place during the course of one day, on a hospital campus. The source for Cristofer's inspiration was his personal experience with two close friends dying of cancer. Offering varying perspectives of characters, comprising three different plots, gives the work a certain objectivity in its discussion of a sensitive subject.
