Luca Cupiello, like every Christmas, prepares the crib, amid the disinterest of his wife Concetta and his son Tommasino. Ninuccia, the other daughter, writes a letter to her husband in which she communicates that she leaves him for her lover. The letter happens in the hands of Luca who hands it over to his son-in-law, who thus learns of his wife's betrayal. During lunch on Christmas Eve, the two rivals, who were confronted by Luca's carelessness, clash violently.
Unfortunately the movie Natale in casa Cupiello is not yet available on HBO Max.
