Mario and Teresa are a seemingly happy marriage, but she reproaches that he does not value enough her work at home. As he is not willing to recognize the importance of domestic chores, Teresa offers him to exchange roles. While Teresa gets a job, and develops very well, Mario is unable to keep the house in order.
