Attempted Flight (1976)

The twelve year old Ivo has been living in Vienna with his family for three years. His father and brothers work at construction sites. Their Austrian neighbors despise the Yugoslav guest workers. Because the mother has to look after the sick grandmother at home in Croatia, Ivo runs the male household in Vienna alone. Solitude and insults from the locals make the child unhappy. And so Ivo decides on a rainy winter's day to return to his home village on his own.
