This movie is based on real events. In February 1977 a 13 year-old boy has been taken into custody inthe city of Graz. This boy has been growing up in the “slums” (meaning the last barracks in the Styrian capital Graz), has 11 siblings and has been raised by his single mother.
Martin Pittner does not see anything bad in breaking-and-entering with his friend – the 13 year-old Fritz – and even commits muggings later on. Not until a detective takes him to task does he realise the gravity of the situation.
