Struggling to graduate from NYU and afford her microscopic studio apartment, Nanny takes a position caring for the only son of the wealthy X family. She rapidly learns the insane amount of juggling involved to ensure that a Park Avenue wife who doesn’t work, cook, clean or raise her own child has a smooth day. When the Xes’ marriage begins to disintegrate, Nanny ends up involved way beyond the bounds of human decency. Her tenure with the X family becomes an impossible mission to maintain the mental health of their four year old, her own integrity and, most important, her sense of humour. Over nine tense months Mrs X and Nanny perform the age-old dance of decorum and power.
