Molly Gunn (Brittany Murphy) is the freewheeling daughter of a late rock legend, and the toast of the Manhattan social scene. But when her inheritance is stolen, Molly is forced to do something she's never done before - get a job. Molly becomes a nanny to precocious Ray Schleine (Dakota Fanning), an eight-year-old going on forty. Emotionally distant from her fast-paced A&R executive mother, Roma (Heather Locklear), Ray has grown up with a revolving door of nannies and too little stability. Molly and Ray both feel painfully alone in the world, but as they try to make their new arrangement work, each discovers in the other a true friend.
