The story of Mel and Edna ( Jack Lemmon and Anne Bancroft ), a middle-class, middle-aged, middle-happy couple living in a Manhattan high rise apartment building. Mel loses his job, the apartment is robbed, Edna gets a job, Mel loses his mind, Edna loses her job . . . to say nothing of the more minor tribulations of nosy neighbors, helpful relatives, and exact bus fares. The couple suffers indignity after indignity (some self-inflicted), and when they seem on the verge of surrender, they thumb their noses defiantly and dig the trenches for battle.

Peter Sellers stars as Harold Fine, a self-described square--a 35-year-old Los Angeles Lawyer who is not looking forward to middle age and his upcoming wedding. His life changes, however, when he falls in love with Nancy, a free-spirited, innocent, and beautiful young hippie. After Harold and his family enjoy some of her "groovy" brownies, he decides to "drop out" with her and become a hippie too. But can he return to his old life when he discovers that the hippie lifestyle is just a little too independent and irresponsible for his tastes?
