The Promise is the story of a rich young college man Michael who falls in love with a poor painter Nancy and wants to get married. However, Michael's widowed mother, Marion is opposed to the match; she wants Michael to take over the family business, and she's convinced that Nancy would be a bad influence. Disregarding his mother's wishes and while on the way to getting married, Nancy and Michael are in a tragic auto accident--he falls into a deep coma and she suffers severe facial disfigurement. Neither Nancy or her family have the money for plastic surgery; Marion agrees to pay for Nancy's facial reconstruction, but only under the condition that she change her name and never see Michael again. Nancy has little choice but to agree, and she changes her name to Marie; and becomes a famous photographer. Years later "Marie" meets Michael accidentally, unknowingly, at one of her art shows and their love begins anew.
