The monotonous life of a bourgeois family is disturbed by the announcement of the imminent return from America of Mr. Lohengrin, who had left Italy years earlier, leaving behind the reputation of being an irresistible womanizer. Lohengrin's cousin, worried about the stability of his marriage, convinces some relatives who live in the countryside to welcome the dreaded guest into their home and then, to avoid meeting him, leaves. Meanwhile, in the country house everyone eagerly awaits Lohengrin, and envy and spite are unleashed during the wait. In particular, while the young landlady prepares the house, the woman's husband begins to be tormented by jealousy. But the arrival of the long-awaited guest will be a huge disappointment for everyone: the once seductive man is now just an aged, with glasses and a prominent belly.
