Sabine Kleist, Aged Seven(1982)

Original title: Sabine Kleist, sieben Jahre

Little Sabine has spent her childhood in an orphanage after her parents died in a car accident. When one of the women in charge at the orphanage, Edith, leaves to have a baby, Sabine runs away, because Edith was the only adult there she could trust. She then wanders through the city to find someone to take her in. She meets a lot of people on her journey, but she seems out of place everywhere she goes until, at last, she realizes that there is a special place where she belongs.
