In a maternity hospital, young single mothers are accompanied by social worker Hélène Lambert, who tries to make them aware of their new responsibilities, while Dr. Baurain stresses the importance of their moral and sexual education. They come to the aid of several young women: one who would like to give up her child to a couple applying for adoption, another who, after the death of her first baby in dramatic circumstances, is expecting a second, and many others.

Mme Dutilleux dirige une maternité, secondée par une assistante sociale et un médecin. Tous trois se sont donné pour mission d'insuffler l'amour maternel à des filles-mères, souvent désespérées.
