In seaside Italy, a Holocaust survivor with a daycare business takes in a 12-year-old street kid who recently robbed her.

25-year-old philosophy major Marta faces the ugly truth for many young Italians — a complete lack of career opportunities. While babysitting for single mother Sonia, she starts to work as a telemarketer, experiencing first-hand the fanatical and exploitative rat-race culture pushed on employees while quickly rising through the ranks of the company. Around her revolve people like delusional supervisor Daniela, her womanizing boss Claudio, fragile coworker Lucio "2", and well-meaning but inconsistent union rep Giorgio.

Madame Rosa lives in a sixth-floor walkup in the Pigalle; she's a retired prostitute, Jewish and an Auschwitz survivor, a foster mom to children of other prostitutes. Momo is the oldest and her favorite, an Algerian lad whom she raises as a Muslim. He asks about his parents; she answers evasively. As she ages and takes fewer children, Momo must do more for her; as money is tight, he tries to earn pennies on the street with a puppet. He's a beautiful man-child, and Madame Rosa makes him promise never to sell himself or become a pimp. A film editor, Nadine, befriends him, and his father appears as well. Madame Rosa reaches her last days in fear of hospitals, and Momo must act.
