描述：　　Two sisters, aged 5 and 8, hang out alone at home in the middle of the countryside. Elsa, the youngest, swallows three grains of coarse salt. Judith announces to her that she’s doomed to a death by desiccation, and she only has a few hours to live. The mother returns, behaving ardently and feverishly, and turns the family's destiny upside down.
