Watch Der Zwerg im Kopf (1991) Official Trailer

Anna is an only child and the child of divorced parents. Her parents get along reasonably well and are quite considerate toward Anna. One day, she discovers the dwarf, a tiny creature that she puts in her ear. When he is not asleep, he interferes in the little girl's problems. Anna has more than she can handle: living with her busy father, afternoons with her actress mother, her first day at school, her unpleasant neighbor Hermann, who falls in love with Anna. The latter was mistakenly caused by the dwarf, even though Anna is interested in Peter.
