Thirty-year-old Emilie runs a hairdressing salon where she provides an endless stream of well-meaning advice to her clients and friends, but the only person she cannot seem to help is her own mother. Jean, a young man who works for Emilie, is secretly in love with her but a pathological shyness prevents him from declaring his feelings. Finally, unable to contain himself, he opens his heart in a passionate anonymous letter, but Emilie has other plans.
