In 1943, during the war, Francesca, widowed, moves with her three daughters to her country house, to get away from the bombing of Bologna. In the villa she finds her childhood friends and her old love Guido, who has not forgotten her. Francesca has a passion for everything that comes from America, like music and cinema. She even tells her daughters that her husband who died in the war would actually leave for the USA, where he would live.

At a farmhouse, a large family cooks mountains of food for the next day's engagement party for Silvia and her city fiancé, Angelo. Her parents feud about infidelity; an aging salesman who rents a cottage from them arrives with a young French woman; in Bologna, Angelo's mother frets that her son is marrying beneath him; his sisters are less critical. Early the next morning, the four of them go by train to the farmhouse, joined by Angelo's married, unpregnant sister. The day-long dinner is riotous, couples display affection and impatience, children chase angels. Angelo's family stays the night, and his sister Linda has a visitor. A silver elephant makes the perfect gift.
