Based on the 2000 book of the same name by Emmanuel Carrère, it is inspired by the real-life story of Jean-Claude Romand. L'Adversaire's protagonist Jean-Marc Faure (Auteuil) pursues an imaginary career as a doctor of medicine in a plot more closely based on Romand's life and Carrère's book than was Laurent Cantet's 2001 film L'Emploi du Temps. The film was nominated for a Palme d'Or at the 2002 Cannes Film Festival.
Marianne Winckler relocates to the port city of Caen in order to pass herself off as a member of a large community of itinerant workers desperate to make ends meet. She gains employment as a cleaner on a ferry travelling between Ouistreham and Portsmouth, recording the drudgery of the work she and her colleagues are required to do.
One day, on a whim, Marc decides to shave off the moustache he's worn all of his adult life. He waits patiently for his wife's reaction, but neither she nor his friends seem to notice. Stranger still, when he finally tells them, they all insist he never had a moustache. Is Marc going mad? Is he the victim of some elaborate conspiracy? Or has something in the world's order gone terribly awry?
