Romantic comedy based on the novel by Winifred Watson. Frances McDormand stars as Miss Pettigrew, a dowdy governess struggling to find employment in 1930s London after being unfairly dismissed from her previous job. She unexpectedly finds herself fulfilling the role of social secretary for glamorous American actress and singer Delysia Lafosse (Amy Adams), whose life is an unending social whirl - the complete opposite of Miss Pettigrew's own drab existence. Despite their differences, Miss Pettigrew becomes Delysia's confidante and personal aide, and is witness to many of the joys and indiscretions that thrive in this heady, high-society climate. Could it be that Miss Pettigrew has finally found her calling?
