Two Pennies Worth of Violets (1951)

Thérèse, a young flower girl, tries hard to remain virtuous but the whole world seems to conspire against her, whether her petty Paris family, or her relatives in the province bristling with false respectability, or her lustful employer, or the boy she loves who seduces her and abandons her. But at the end of the day there is Yvon, her childhood friend. Will he be the one that will love her truly?
