Fran has just been fired from her job as a bridal consultant by her ex-fiancé, Danny, and Maxwell mistakenly believes that she has been sent by a nanny agency and quickly hires her to be nanny to his three kids. Fran appears at the doorstep of a wealthy widowed Englishman, Broadway theatrical producer Maxwell Sheffield (Charles Shaughnessy), while selling cosmetics. The Nanny is primarily based upon the story of nasal-voiced Fran Fine (played by Fran Drescher) who is from Flushing, Queens.
