Breating (Atmen) is the 2011 debut film by Karl Markovics about a juvenile detention prisoner and his experiences while working at a municipal morgue. Synopsis as follows (via Quinzaine):

“Roman Kogler, 18, is serving time in a juvenile detention center. He has already served half of his sentence, and could be released on probation, but his chances are poor: he doesn’t have family, and seems incapable of coping with society. After many failed attempts, Roman finds a probation job at the municipal morgue in Vienna. One day, Roman is faced with a dead woman who bears his family name. Even though it soon turns out that she is not his mother, Roman wonders about his past for the first time and starts looking for his mother.”
