Beauty Fiora was raised by her adoptive father, a prosperous Florentine merchant, who hid the shocking secret of her origin from everyone. The noble Frenchman Philippe de Selonger, who learned this secret, agreed to keep it only for the right to make Fiora his wife and spend only one wedding night with her, and then immediately leave. Fiora, meanwhile, is forced to go to France in order to find out the truth about her birth.
