Things are looking up at last for Lizzie Nichols. She has a career she loves in the field of her choice (wedding gown restoration), and the love of her life, Jean-Luc, has finally proposed. Life's become a dizzying whirl of wedding gown fittings - not necessarily her own - as Lizzie prepares for her dream wedding at her fiancé's château in the south of France.

But the dream soon becomes a nightmare when the best man - whom Lizzie might once have accidentally slept with...no, really, just slept - announces his total lack of support for the couple, a sentiment seconded by the maid of honor; Lizzie's Midwestern family can't understand why she doesn't want to have her wedding in the family backyard; her future French in-laws are trying to lure the groom back into investment banking; and Lizzie finds herself wondering if her Prince Charming really is as charming as she once believed.
