This crafty French mystery-thriller about a man whose world is turned upside down when he is led to believe that his wife, who was murdered eight years ago, may still be alive weaves its labyrinthine plot in such a way that it constantly forces you to pay attention and fit the pieces together; it is not the kind of film where you can lapse in attention for even a few seconds, much less get up for a bathroom break. Aside from its almost embarrassing use of American pop music to underscore several emotional montages and a few narrative conveniences that feel a bit too convenient, it is an absorbing thriller, one that works its narrative complications over a genuinely moving emotional foundation and is spiked with just enough dark humor to keep it from becoming overly serious.
