One Sings, the Other Doesn't

L'une chante l'autre pas is a movie starring Thérèse Liotard, Valérie Mairesse, and Robert Dadiès. The lives of Pomme, an aspiring singer, and Suzanne, a struggling mother, as they search for their own identity in 1970s France.
In this story of friendship and reproductive rights, 14 years in the relationship between two very dissimilar women are chronicled. Pauline is a middle-class city girl, at odds with her very conventional family. Suzanne is several years older, a country girl with two illegitimate children and another (whom she cannot support) on the way. Pauline loans Suzanne money for an abortion. At this point, the two separate and communicate mainly through postcards. Some years later, they meet at an abortion rally, and they have many adventures and stories to share with one another.
