Lizzie Nichols, a fashion-history major, wants nothing more than to graduate college and then fly off to London to be with her boyfriend, Andy. But at her graduation party, Lizzie finds out that she can't graduate until she writes a senior thesis. And when she lands in London, Andy turns out to be a liar, gambler, and a fashion disaster. Lizzie, stuck in London with a nonchangeable ticket home, escapes Andy via the Chunnel in hopes that her friend Shari, who is catering weddings for the summer at a French chateau, can help. On the train, Lizzie meets a stranger, Jean-Luc, and spills everything that has happened, only to find out that he is the son of the chateau's owner. At the chateau, Lizzie continues to babble when she shouldn't, ticking off Jean-Luc, shocking his mother, and upsetting a bride. Will she ever learn to keep her mouth shut?
