When an eco-friendly sister takes sweet vengeance on her sex-in-the-city socialite sibling, our shallow, materialistic heroine avoids destitution by joining forces with the new-age family her sister left behind. Condemned to the purgatory of working as an au pair for a family who prefer lentil stew over Beef Wellington, she is forced to swop Harvey Nichols’ Prada for Charity Shop Primark, and bring forth the maternal instincts that she’d happily traded in at birth for a glitzy London career. Despite her determination to remain unsullied by the hippy lifestyle she is forced to inhabit, she forms an unlikely alliance with her three young charges. Lovers for breakfast and spiritual choices no deeper than deciding which Alexander McQueen outfit to wear with her latest impossibly high heels, is the life she left behind and desperately wants back. But our heroine falls for a man as deep as she is shallow, and for the first time in her life begins to build - and fight for - relationships that actually mean something. In this fast-paced, wickedly funny satirical comedy, our anti-heroine learns that on the way to getting even, being square isn’t all it’s cracked up to be.
