Ten years after the fateful night when Nan was fired, she returns to New York with her husband, HH. Finally settling in to build a permanent home and get her consulting business off the ground, Nan's plans are derailed by HH's sudden desire to start a family - and her surpisingly strong resistance to the idea.
Matters are further complicated by a late-night, drunken visit from a now fifteen-year-old Grayer, who's stumbled upon the nanny-cam tape Nan made on her last night in his mother's employment - and wants some answers. Racked with guilt and struggling to find a way to help Grayer and his seven-year-old brother, Stilton, through their parents' vicious divorce, Nan finds herself getting sucked into the Upper East Side world of wealth, power and dysfunction all over again.
Set against the backdrop of a Manhattan economy cracking along the fault lines, The Nanny Returns plumbs the humour and heartbreak of a community who chose money over love, only to find the money evaporate - and their children ready to tell all.
