Ghosted by her hunky twenty-something lover, Claire (Juliette Binoche), a middle-aged professor and single mom, creates a fake Facebook profile to do a little undetected online snooping. But when her 24-year-old avatar “Clara” is friended by her ex’s equally attractive roommate (François Civil), superficial correspondence quickly escalates towards intense intimacy and uncontrollable obsession. Binoche balances cunning and vulnerability in this romantic cyber-drama turned psychological thriller from writer-director Safy Nebbou, adapted from Camille Laurens’ best-selling novel.
