The tragic love story between Guido, the owner of a marble quarry and Luisa, the humble daughter of one of his employees, ends up in her giving birth to their baby boy. Giulio's mother is against them: first she sends her son abroad and then has the baby kidnapped, making Luisa think the boy died in a fire.

In this sequel to Nobody's Children, Guido still longs for Luisa, who has become a nun. Then he meets Lina, a chorus dancer who is a dead ringer for his former lover.
