Ab mit dir ins Vaterland (1980)

Eleven year old Stefan no longer knows his identity: is he Polish or German? Until now he has been Polish, and now that his family has moved to West Germany, he is supposed to be German? But there's the foreign language, the big city with its supermarkets and the lack of friends. In the end, Stefan leaves home and travels back to his hometown illegally. But he can't find his way around there either. Until Stefan knows where he belongs, he has to make many detours.
