Fran, fresh out of her job as a bridal consultant in her boyfriend’s shop, first appears on the doorstep of Broadway producer Maxwell Sheffield peddling cosmetics, and quickly stumbled upon the opportunity to become The Nanny for his three children. But soon Fran, with her offbeat nurturing and no-nonsense honesty, touches Maxwell as well as the kids.
C.C. and Niles get married while Fran is in labor and find out that they are also expectant parents. Maggie and Brighton head off to Europe as the Sheffields head to California with the new twins and a new life together.
