The story of Streetcar is about how the faded and promiscuous Blanche DuBois leaves her once-prosperous situation, after encountering a series of personal losses, to move into a shabby apartment in New Orleans rented by her younger sister Stella and brother-in-law Stanley.  The story concerns her mental and moral disintegration and ultimate ruin, as her neurotic and genteel pretensions are no match for the harsh realities symbolized by the brutish Stanley.  She eventually loses her grip on reality as she fails to get what it is she most desires.
