When Nola Devlin is turned down for her dream job because she's overweight, she decides to become thin--or, at least, pretend to be. The alter ego she creates--the thin, British, hip, and did we mention thin Belinda Apple-is a smashing success who is offered movie proposals, national television appearances and even dates... though no one's met her in person, of course.

Then Nola takes Belinda a bit too far, and is forced to join "The Cinderella Pact" and drop the pounds. As the weight comes off, however, Nola's problems begin to mount.
