My Piece of the Pie (2011) on Netflix

Plot summary

France has spent twenty years working for a shipping company in Dunkirk, where she raises her three daughters. When the company closes, she and her workmates lose their jobs. She goes to Paris to look for work there and enrolls in a housekeeper training program, pretending to be a low-skilled immigrant so she can take whatever jobs come her way. A wealthy banker who has just returned from ten years in London hires her to clean his Paris apartment. His world is not hers, and the two are tense with each other at first.
