Sigismond Langlois is submitted to a psychiatric evaluation on account of his violent behavior. He just turned 18, and pretends he was born with no image. Throughout the questionnaire, he recounts the peculiar existence of a young man who never saw himself, neither in reflection nor on photo, to the point of sometimes doubting of his own existence. But today, Sigismond is determined to make himself heard.

Louis, a terminally ill writer, returns home after a long absence to tell his family that he is dying.
