Fabio is in love with his colleague Linda, but she has never even seen him until he's mistaken for her boyfriend. Paolo and Mario leave for a luxurious vacation in Rio de Janeiro for Christmas, without knowing that their sons have booked a trip for the same low-cost destination and, for a problem of homonymy between fathers and sons, the two holidays are exchanged.
