Marc (Vincent Lindon) has worn a mustache all his adult life. One day on a whim, he decides to shave it off. Certain his wife will comment on the drastic change in his appearance, Marc is baffled when neither she nor friends notice at all. Even more disturbing is that once he calls attention to it, everyone insists he's never had a mustache. Emmanuel Carrere's film adaptation of his novel won a 2005 Cannes Directors' Fortnight award.
