Marc (Vincent Lindon) gamely waits, in vain, for Agnès (Emmanuelle Devos) to notice his newly hairless lip. She betrays not the slightest reaction, and when pressed on the matter insists he never had a mustache. Friends and colleagues are similarly oblivious to the change in Marc's appearance, and he suspects Agnès has masterminded an elaborate practical joke. But his suspicions take on a darker tinge as days go by. Is Agnès gaslighting him, or is Marc in the throes of a midlife breakdown? Intuiting that he's experiencing something beyond logic -- or doubting his own eyes -- Marc doesn't force Agnès to look at an album full of snapshots in which he's smiling and mustachioed. Overhearing her plans to hospitalize him, he flees the country, Philip Glass's well-chosen "Concerto for Violin and Orchestra" the frenzied accompaniment to his rain-soaked cab ride to the airport.
The concise film enters unexpected territory, physically and psychologically, in its final, Hong Kong-set section. Marc immerses himself in calming views of the harbor, the crowds' orderly bustle and, especially, the lulling back-and-forth of the ferry. He's a man in between, unmoored, but in this foreign place his otherness is clear, definable and unchallenged. With one last surprise before closing credits, Carrère poses questions about the untranslatable places in our emotional lives and how the existential fact of separateness can threaten agreed-upon roles -- especially in marriage. "La Moustache" uses sly wit and foreboding to deconstruct notions of self in its portrait of a close shave with insanity.
