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.
