On her wedding day, a woman is abandoned by her mafia fiancé after he leaves her for another woman who has just given birth to his son. He cruelly gives her the sick and disabled baby to raise, saying he might return if the child grows strong. Believing the boy only has a short time to live, she gives him up for adoption and turns to Constantine, a man who had always loved her. Constantine marries her immediately, and five years later she becomes the respected and feared Donna of the powerful Moretti family. Together, they raise a brilliant young boy. When her ex-fiancé suddenly returns with his new wife, he mistakes the child for his own and violently tries to take him away, forcing her to protect her son until Constantine arrives.
