Paris, 2015. A crowd gathers outside the Chauvet home in the affluent suburban community of Maisons-Larue, watching as the family's American au pair is led away in handcuffs after the sudden death of her young charge. The grieving mother believes the caretaker is to blame, and the neighborhood is thrown into chaos, unsure who is at fault--the enigmatic, young foreigner or the mother herself, who has never seemed an active participant in the lives of her children. The truth lies with six women: Géraldine, a heartbroken French teacher struggling to support her vulnerable young students; Lou, an incompetent au pair who was recently fired by the family next door; Charlotte, a chilly socialite and reluctant mother; Nathalie, an isolated French teenager desperate for her mother's attention; Holly, a socially anxious au pair yearning to belong in her adopted country; and finally, Alena, the one accused of the crime, who has gone to great lengths to avoid emotional connection, and now finds herself caught in the turbulent power dynamics of her host family's household.
