The young girl tells us that her mom's new friend is just like the big bad wolf. At first the wolf is sweet and kind to her mom, though the girl notices the wolf's cold eyes from the very beginning. When her mom arrives home late one day, the wolf suddenly hurls angry words and terrible names at her. From that day on her mother doesn't smile anymore. The girl is careful to clean her room and brush her teeth and do everything to keep the peace, but the wolf is unpredictable, throwing plates on the floor, yelling at her mother and holding the girl's arm so tightly she is left with bruises. Whenever the yelling begins, she hides under the covers in her room. How will she and her mom cope as the wolf becomes increasingly fierce?
