The job seems like a dream come true for Sarah Larsen: a glamorous penthouse apartment on the Upper West Side; a salary that adds several zeroes to her current income; the beautiful, worldly mother of her charge, who feels more like a friend than a potential boss. She signs the NDA without a second thought. But there is something very strange about the Bird family. Why does the beautiful Mrs. Bird never leave the apartment alone? And what happened to the nanny before her, who disappeared under mysterious circumstances? It soon becomes clear that the odd behaviors Sarah initially dismissed as the eccentricities of the wealthy are hiding something much darker and more sinister. But by then it's too late for Sarah to seek help. And, after all, discretion is of the utmost importance.
