When a house in the neighborhood is put up for sale, Archie starts a petition to keep ethnic groups out. Henry Jefferson joins the effort when a Hispanic couple show interest. All this happens during a stifling heat wave in New York City.
A September heatwave causes tempers to flare up in the Bunker house. Mike won't leave Archie alone about Watergate, Archie destroys the air conditioner, a Puerto Rican family is about to buy the house next door and Archie and Henry draw up a notice to keep them from moving in. The Puerto Rican family moves on but the house is then bought by The Lorenzos, she is Irish and can fix anything and he is Italian and won't stop singing.—Jerry Roberts <armchair-cinema@hotmail.com>
