Elisa and Eric are two teenage war orphans. They change their apartment on the outskirts of the city into a photo-studio to make a living, and they are very devoted to it. The two seem to live like heavenly beings without connecting to the outside world. Their only contact with the exterior is through Jacques, a loyal friend, but he also cuts himself out of any social life. The sister and the brother then take to get in touch with the world by Mrs Jean, a friend of their deceased mother with whom Elisa takes courses of singing. They live in harmony until a young man, whom Elisa falls for, eventually leaves with Eric for the USA and left her brokenhearted alone in France.

France, World War II. In order to somehow make ends meet, the mother of two children, Marie Latour, does underground abortions and rents a room to a familiar prostitute. She doesn't pay any attention to her husband, who returned from the war because of his injury, and lives her own life. Abortions gradually begin to bring a good income, and boredom can be easily dispelled by starting up with a young lover.
