Emily, une Américaine d'une vingtaine d'années originaire du Midwest, part s'installer à Paris après avoir reçu une proposition d'emploi des plus inattendues. Son nouveau challenge : apporter un point de vue américain à une agence de marketing française en difficulté. Alors qu'un vrai choc des cultures l'attend, Emily va devoir jongler entre sa carrière, sa vie amoureuse, et de nouvelles amitiés naissantes.

The story revolves around Estelle, an incomparably professional long-haul pilot/captain who leads a perfectly structured life alongside her loving and protective husband Guillaume. Everything seems to be going well, although the endless flights and bouts of "jet lag" are beginning to upset the young woman’s biorhythms, especially her sleep. One day, in a corridor in Nice airport, she randomly crosses paths with Ana, a photographer she’d had a passionate affair with twenty years earlier. Estelle has no way of knowing that this reunion will suck her into a nightmaresque spiral and lure her life into irrationality...

Stéphanie, a police officer working for Internal Affairs, is assigned to a case involving a young man severely wounded during a tense and chaotic demonstration in Paris. While she finds no evidence of illegitimate police violence, the case takes a personal turn when she discovers the victim is from her hometown.

One morning, Louise, 45, is suddenly unable to step out of her car. Sweats, anxieties, palpitations... she is having an inexplicable panic attack. She is tetanized and simply cannot set foot outside.
