Twelve-year-old Anna switches from middle school to high school. Things are quite different here: the children in the new school come from a completely other social class. Anna feels ashamed of her background and her deaf mother. During the ski week, Anna must pretend to be sick. The money set aside for the ski course is spent on buying a sofa bed, which should enable her mother to have a sexual relationship, but also provide the daughter with a bit more privacy. Mara, a friend in class, becomes an ally when it turns out that she also is hiding a secret.
