When Jo Green takes a nannying job in London to escape her small-town routine and perfect-on-paper boyfriend Shaun, culture shock doesn't even begin to describe it. Dick and Vanessa Fitzgerald are the most incompatible pair since Tom and Jerry, and their children glittery warrior pixie Cassandra, bloodthirsty Zak and shy little Tallulah are downright mystifying. Suddenly village life seems terribly appealing. Then, just as Jo's getting the hang of their designer lifestyle, the Fitzgeralds acquire a new lodger, and suddenly she's sharing her nanny flat with the distractingly good-looking but inexplicably moody Josh. So when Shaun turns up, things get even trickier.
