A deliciously entertaining Cinderella story for grown-ups. Inept governess Guinevere Pettigrew is homeless, jobless and broke. Waiting patiently at an employment agency she gets a new position but instead of the usual fraught mother and fractious brood she encounters Delysia LaFosse. A glamorous nightclub singer with man trouble, Delysia is in dire need of Miss Pettigrew's peculiar blend of blunt honesty. In return Miss Pettigrew is swept into Delysia's risqué world of beaus, beautiful people, negligees and nightclubs. Across moral and social divides a surprising bond grows, and by the end of the day, both their lives have been transformed.
