Nuccia Aronne

In 19th-century Naples, Doctor Pisani is a patriot unjustly accused of having killed a marquise. He does not want to betray the cause and allows himself to be executed. Ten years later, his son Oliviero, who becomes an ophthalmologist, uncovers the truth and wants to marry Béatrice, the Marquise's daughter, who became blind during the assault on her mother's castle by revolutionary patriots.

Barbara Florian is in love with Renalto Baldini. After the latter goes off to a distant job to make enough money to marry her, the girl discovers she is going to have a baby. Marco (Otello Toso), posing as a friend, exploits the situation to his own gain, and uses the situation to shock the girl's ailing father to his death. Marco then marries the widow, Valeria (Franca Marzi), the girl's stepmother.
