Who You Think I Am

Claire, a middle-aged professor of French literature, shares custody of her two sons with her ex-husband Gilles. She carries on an affair with the younger Ludovic, who obviously sees it as more casual than Claire. He soon distances himself from her, and when she calls, his roommate Alex answers the phone and pretends Ludo is out.

Claire creates a fake persona, "Clara Antunès", on Facebook, to connect with Alex, gradually developing an emotional and cybersexual affair with him. When Alex grows insistent upon meeting in person, Claire, as Clara, says she's getting married and moving to Brazil, calling off the affair rather than risk a meeting. Alex deletes his profile, leading Claire to approach Ludovic to find out about him. He tells her that Alex, broken-hearted over a "psychopath" on Facebook, has killed himself.

These narrative details are revealed through a series of psychotherapy sessions between Claire and Dr Bormans. Bormans asks Claire to be honest about a detail in her story that does not add up, leading Claire to disclose that the photos and videos of "Clara" used during her communications with Alex actually belong to her estranged niece, Katia, whom she brought up.

Bormans receives a dossier from Claire containing a story in which she makes Alex' acquaintance alter the end of the "Clara" persona. In the story, Alex and Claire become live-in lovers, but a nagging doubt over whether "Clara" retains a place in his heart leads Claire to revive the persona and ask Alex for a meeting. Alex, trying to ring "Clara", finds the hidden phone Claire had used for "Clara"; returning to confront Claire, he unnerves her to the point where she walks backwards into traffic and is presumably killed. Bormans concludes from the story that Claire is unwilling to allow herself any happiness, even in a work of fiction. It's revealed that Claire is a patient in a clinic for treatment of a mental disorder.

Later, Bormans seeks out Ludovic, who reveals that, having heard "Clara's" voice in one of her calls to Alex, he had seen through her and later invented the story of Alex's death. Dr. Bormans brings this information to Claire, who confesses that it was for her niece Katia that Gilles had left her. Claire now appears ready to leave the institution.

In the last scene, Claire dials Alex's number from "Clara's" phone.
