Adapted from the best-selling novel, the whimsical, heartwarming comedy The Nanny Diaries concerns Annie Braddock (Scarlett Johansson), a recent college graduate from New Jersey whose nurse mother makes an unsuccessful bid to pressure her into a white-collared business career. Sidetracking this path for more colorful pursuits, Annie accepts a position as nanny and domestic servant for a wealthy couple on the Upper East Side of Manhattan, known only as "The Xs" (Paul Giamatti and a heavily coiffed and accoutred Laura Linney). Annie has her first real taste of servant life when she arrives at the family's residence and promptly sinks into Mrs. X's luxury tub, but is soon shuttled off to her own bare-bones room. Face to face, for the first time in her life, with the vast socioeconomic differences between herself and others, Annie must spend her days catering to Mrs. X's every whim, navigating the emotional land mines set by the domineering Mr. X, and tending to the demands of the couple's mischievous and bratty son, Grayer (Nicholas Art). The situation grows a bit more awkward and sticky when Annie begins to fall for a young man who lives near the Xs, whom she's nicknamed Harvard Hottie (Chris Evans), leading her to seriously reevaluate her career goals and priorities.
