Nunzio Giuliano

Back from the hospital where he has been treated after a heart attack, Lorenzo is on his way upstairs to his top-floor apartment in Naples when he meets Michela. The charming young woman, who has just moved to the facing apartment, has forgotten her keys and finds herself locked out. Cynical and grumpy, the retired lawyer who has been living estranged from the rest of the world, should normally leave her to her fate but he mellows under her spontaneous charm. He helps her, becomes friends not only with her but with her husband Fabio and their two children. For once, the self-declared misanthropist seems to be experiencing the long forgotten feeling of empathy.

Giulio is a widower, struggling to raise three sons, Marco, Rudi, and Mimmo, as best he can. He lives in Rome's working-class Garbatella neighborhood and runs a wine shop with his two brothers. Lucia, meanwhile, comes from Milan's middle-class background; she's divorced and trying to rebuild her life with her two daughters, Eva and Alice. The two meet by chance and recognize each other: they had a fling as teenagers, many years earlier. Yet first love is never forgotten, and so Giulio and Lucia find themselves together again. Their meeting, however, changes not only the lives of a man and a woman, but also those of two families as different as could be. Two families who find themselves living under the same roof without even having had the time to get to know each other well.
