Seventeen-year-old Katie is overwhelmed when she lands a job as a nanny for Premier League soccer player Brett Ballentine and his wife Kassie's kids. Arriving at the Ballentine mansion in London, Katie feels as though she's living in a magazine. She's got a whole floor of the house to herself, her own car, and the inside scoop on Britain's most notorious celebrity couple. But there is a downside. Katie has to learn to keep her mouth shut when it comes to some of Kassie's strange and desperate behavior. And Brett is like the ice man -- he barely acknowledges her. As time goes on the "happy couple" reveal their true colors, and the true state of their volatile marriage. Kassie has a twisted secret, and Brett's getting too fond of "playing away." Katie feels like she and the kids are caught in the middle of a war zone, culminating in a shocking revelation about Brett. But while Katie struggles with her predicament, a budding young photographer snaps the picture the tabloids have been waiting for and catapults herself into the limelight.
