Mrs. Harris Goes to Paris tells a humorously heartwarming tale about a London housecleaner Ada Harris (Lesley Manville) who thinks her lonely life might turn around if she can become the owner of a Christian Dior gown. Saying goodbye to friends like Archie (Jason Isaacs) won't be easy, and neither will be winning over elite people in Paris from Madame Colbert (Isabelle Huppert) to idealistic accountant André (Lucas Bravo). But Ada's irrepressible charm just might end up saving the whole House of Dior in this uplifting story of how an ordinary woman becomes an extraordinary inspiration by daring to follow her dreams.
