At a political rally, bricklayer Oreste (Marcello Mastroianni) sees flower girl Adelaide (Monica Vitti) and is so thoroughly smitten that he decides he must leave his wife for her. The pair's happiness doesn't last, however, as a young pizza chef named Nello (Giancarlo Giannini) also has eyes for Adelaide. He sends her a heart-shaped pizza pie and in no time has broken up their relationship. Adelaide leaves Oreste, who becomes passionately grief-stricken and considers suicide.
