Mirella and Howard appear to have it all: two careers, two kids, a beautiful house in the Boston suburbs. And like most couples living the American dream, their lives are hectic, the house is a mess. Worse, both children seem troubled. Enter Randi, the ideal nanny, who cooks, cleans, does craft projects, and takes the children to heart.

But as Mirella and Howard settle gingerly into this perfect arrangement, disturbing cracks appear in their home life. Are the children becoming too attached to Randi? What don't Mirella and Howard know about her? And what don't they know about each other?
