“What would you say if I shaved off my moustache?” Marc asks Agnès. Just to see how she’ll react, he shaves off his moustache. She comes home and doesn’t notice a thing. No one else notices, either. Marc stands alone, the only one convinced that until the day before he’d had a moustache. He’s the only one who can see it in old photos. He’s the only one to believe, to see, to remember – he feels like he’s going crazy.
