Solange, the Malian governess and mother of a large family, Fanny, the down-and-out bourgeois woman at the end of her rope, Michèle, the loud-mouthed queer activist... Three women who have nothing in common and yet will unite around a fight: a chambermaids' strike, a priori doomed, which will turn their lives, their principles, their vision of themselves upside down, taking them out of their solitude by finally making their unfortunate sisters visible and audible.
