Annies mother (Donna Murphy) is pressuring her to take a job in business but Annie has more interest in anthropology. After blowing her first interview with a New York financial firm Annie heads to Central Park to mull over her options. As fate would have it its there that she meets Mrs. X (Laura Linney) a wealthy mother from the Upper East Side. Mrs. X happens to witness a warm interaction between Annie and her son Grayer (Nicholas Art) and mistakenly assumes Annie is a nanny. She immediately offers Annie a job and despite the warnings of her best friend Linette (Alicia Keys) Annie takes it. She decides to approach the job like an anthropologist in the field and she is alternately fascinated and appalled by her observations. Despite their luxurious lifestyle the Xs are revealed to be a truly dysfunctional mess. Annie quickly learns that money might indeed buy you a house on Nantucket but it certainly cant buy you an honest husband or the affection of your son.
