The film begins in a flashback from the titular character, Antoine. We are introduced to his fixation with female hairdressers which began at a young age. The film uses flashbacks throughout and there are frequent parallels drawn with the past. Though Antoine tells Mathilde that 'the past is dead', his life is evidence that on some level the past repeats itself. As a young boy he fantasised about a hairdresser who committed suicide and as a man in his 50s he begins an affair with a hairdresser which ends after ten years in her suicide. However, there are differences, Mathilde commits suicide because she is so happy she is afraid of the happiness she has found with Antoine ending.
