La Face cachée (2007)
Directed by Bernard Campan

Film Synopsis

Isa and François are a couple in their forties who appear to be quite settled in their lives.  They have been together for some time but recently they feel as if they have become strangers.  They no longer know how to communicate with one another and they have become wrapped up in their own private concerns, unsure where their lives are heading.  François is presently in the grip of a severe mid-life crisis and is constantly preoccupied with death.  Nothing seems to interest him any more, and the only person he can confide in is his best friend Xavier.  The latter does all that he can to advise and encourage his friend, but in truth he is just as flummoxed as François is about the whole business.

It would appear that something is driving François and Isa apart, but the former has no idea what this could be.  Isa shows no outward signs of discontent, there are no rows or hysterics, but her partner instinctively knows that their relationship has turned sour.  In the end, François comes to the conclusion that Isa must be having an affair.  His suspicions appear to be borne out when he sees her in the company of another man.  Naturally, François feels he is owed an explanation, so Isa willingly provides him with one.  How easily the lies trip off her lips!  She might almost have been rehearsing this scene for years.  Her unsuspecting partner has yet to see her hidden face...
