London, 1939. It's been a miserable day for Pettigrew (Francis McDormond Frances McDormand), at least at first. As the daughter of a priest, she obeys strict and rigid self-discipline, and puts these restrictions and teachings on the children she brings. Yes, Pettigrew is a home classroom in London, but her strict discipline made her parents so unhappy that she was fired three times in a month. Ms. Holt from the tutoring center also kicked her out this time. Dressed in gray and destitute clothes, she picked up a letter of recommendation for Miss Delysia Lafosse (Amy Adams Amy Adams) and went to her door. Delysia is an amphibious star waiting to shine. In order to get a chance, she deals with three men at the same time, and only one of them is what she really loves. Over the next 24 hours, Pettigrew will help Delysia through thrilling and comic crises and recognize what true happiness is, and Pettigrew.
