 When Betty is caught en flagrante, her bourgeois in-laws and husband force a divorce settlement upon her and bar her from seeing her two daughters. She is rescued from an alcoholic stupor by Laure, a middle-aged woman who takes Betty to her hotel lodgings, extends friendship and care, and listens to her story. Laure s lover, Mario, the proprietor of the bar where Betty and Laure met, is first a friend, then Betty s next conquest.
