i skolen, at han skal gå 3. klasse om, lader han sin vrede gå ud over andre, især ud over Jack fra den nye klasse. Men så kommer mor på hospitalet, moster flytter ind, og hun kan klare uhyret. Langsomt får Emil det bedre, og da han en dag kan hjælpe Vanja fra klassen, fordi han er så stærk, får han også nye venner. In English: Emil lives alone with his mother, who is often very sad and hides in her bed. He is convinced that it is because there is a monster living somewhere hidden in the apartment. The monster has also taken his father, who one day was suddenly gone. Emil is upset and angry, and since he also does so badly in school that he has to go to 3rd grade again, he lets his anger go beyond others, especially beyond Jack from the new class. But then Mom comes to the hospital, aunt Sue moves in and she can handle the monster. Slowly Emil gets better, and since one day he can help Vanja from the class only because he is so strong, he also makes new friends.
