I thought of Tom Ripley desperately trying to keep all his balls in the air, in THE TALENTED MR RIPLEY, of how he almost went nuts trying to play one character off against another--and that was a murder story. Judith/Margot hasn't killed anybody, yet her distress at having to keep up this act is crushing her, and even the viewer a little. The script is either unintentionally vague or deliberately so--I was never able to decide which. We are left with some excellent performances: Quim Gutierrez is outstanding as the extremely frustrated Abdel, never sure of where he stands with 'Margot', and Bruno Salomone as the conductor just drips with self-satisfaction; rarely have I seen a man so unconcerned with being a cuckold. The distress shown by Judith's parents in one amazing scene has to be seen to be appreciated. It's a shame that the story had to be so confusing with performances like these.
I'm a great admirer of Virginie Efira; I've seen a half-dozen or so of her films and she's excellent in both comedy and drama. She's going to have a long career, as Catherine Deneuve has had.
