At the entrance of an ancient cloistered convent, one morning a mysterious basket is discovered, containing a little girl. The nuns, deeply moved by this unexpected occurrence, feel their maternal instincts awaken in the presence of the adorable child. The convent’s mother superior and the respected village doctor, who holds the privilege of entering the sacred grounds, engage in a conversation that leads to a peculiar agreement: the doctor will adopt the girl as his own, but entrust her to the nuns to provide her with a loving and devoted education.
