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.
Cousins James and Robert are in love with Susanna. When Robert and Susanna announce their engagement, James vows to ruin their happiness.
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.
