Desperate for employment to support her three children, she moves to Paris where she connects with Ahmed (Zinedine Soualem), the father of a former co-worker.

France pretends to be a low-skilled immigrant to find menial work, but is then offered the chance to be the housekeeper for Stéphane Delarue (Gilles Lellouche), a wealthy French banker who has returned to Paris after 10 years in London.

The relationship between the pair is initially tense, but Stéphane eventually warms to France, especially after she proves herself an adept hand at taking care of his son for a month, an extra duty for which she is paid €200 a day.

Leaving the hotel to play in the park with Stéphane's son, France then overhears him boasting and laughing about his conquest the previous night.

France abducts the boy and returns to Dunkirk, holing up in an auditorium that's hosting a dance performance.
