Among friends and family, Guido and Maria can't find a moment of peace at home, and this certainly isn't good for the couple. Grandpa Libero, however, due to a series of misunderstandings, thinks Ciccio is taking drugs. Grandpa Nicola makes a grand comeback, but the reality is very different from what he pretends. He invites Maria on a cruise, and she, who initially refuses, eventually realizes that all her grandfather has left is family affection.
