Valentina holds her newborn son. Though hers wasn't a planned pregnancy, she's determined to raise him on her own. But then, several months later, she's informed that he isn't her son after all. Apparently, her baby was mixed up with someone else's at the hospital. The father of the other child, Giovanni, has just gone through a divorce and is also raising his son on his own. When the babies are returned to their biological parents, they won't stop crying. At a loss and determined to do what's best for his child, Giovanni suggests to Valentina that they move in together.
