To Miss Pettigrew, the choice is clear, but to Delysia, marrying for love is the one luxury she cannot easily allow herself. It's clear that her heart lies with Michael, but she cannot deny the temptation of money and fame that the other men can offer.

There's Nick (Mark Strong), the rich owner of the flat where she stays Phil (Tom Payne), a young West End producer eyeing her for the lead role in his upcoming production and Michael (Lee Pace), a handsome working-class pianist who wants desperately to marry her.

Delysia is faced with a choice between three suitors, each with something different to offer. Thus begins a fleeting partnership over the course of a single day, with Delysia offering Miss Pettigrew a glimpse of a world she could never otherwise be a part of, and Miss Pettigrew helping Delysia decide what she really wants out of life. Although Miss Pettigrew, a vicar's daughter, finds the situation morally objectionable, she needs the work and cannot bring herself to abandon the frantic Delysia. On the morning in question, the flighty actress is desperate to get one boyfriend out of bed and out the door before another one arrives. From the moment Miss Pettigrew steps through the front door of Delysia's penthouse flat, she is instantly catapulted into Delysia's madcap world. What Delysia actually requires is a "social secretary," someone to keep her commitments straight and, most importantly, run interference between her various boyfriends. At her employment agency, she surreptitiously acquires the address of one Delysia LaFosse (Amy Adams), an upwardly mobile American actress whom she assumes is in need of a governess. Frances McDormand stars in the title role of Miss Pettigrew, a down-on-her-luck widow living in pre-World War II London who has become known as the "governess of last resort" because of her inability to keep a position for any length of time.
