Christmas at the Cupiello House: Luca Cupiello lives with the wife Concetta, the son Tommasino, and a brother, Pasquale. The son is wild, living by gimmicks and stealing from his uncle; the daughter Ninuccia does not get along with her husband Nicolino and plans to run away with her lover Vittorio; the wife tries to hide her family's troubles from her husband. Luca, who silently suffers the family situation, takes refuge in setting up the Nativity scene.
