"A Raisin in the Sun" focuses on the African-American working-class Younger family, as they dream of leaving behind the run-down tenement apartment where they have lived for many years. The son, Walter, a chauffeur, dreams of making a fortune by investing in a liquor store but foolishly gives his money to a con artist. His sister, Beneatha, a somewhat flighty college student, tries to find her identity and embraces the "back to Africa" philosophy of a Nigerian friend, Joseph Asagai. The family's matriarch, Lena, dreams of buying a home, and does so with her late husband's insurance money, but the house is in an all-white neighborhood. Their racist future neighbors hire a man named Karl Lindner as a "welcoming committee" to try to buy them out to prevent the neighborhood's integration. However, Walter takes a stand and refuses to be intimidated or bought out.
