A man named Bernard (Gerard Depardoo), appears happily married to his pretty little wife and his joyful little boy. And then an old lover, Mathilde (Fanny Ardant), unexpectedly materializes out of nowhere when her husband unknowingly rents the house next door.
A complicated switchback of passion and recriminations ensues. It starts off intriguing, wandering why there relationship ended, wandering when they will cave into their naked desire, and wandering what will happen when their partners find out.
But it quickly descends into a trope infested disappointment, as it becomes reduced to facile conflicts of cardboard archetypes. Bernard becomes the jealous male and Mathilde the hysterical bunny boiler with all the subtlety and nuance of a sledgehammer.
Perhaps this wouldn't matter…
