Directors Christian Rost and Claus Strigel presented their political thriller documentary Unter Menschen (Redemption Impossible) which reveals the suffering of a group of chimpanzees abused in the name of medical research. The animals were infected with HIV and hepatitis in the laboratory. After they had spent 15 years living in isolation, the experiments on the chimpanzees were abandoned without conclusive results. Their subsequent journey into freedom includes a stay in an Austrian safari park and ends at the "Gut Aiderbichl" animal sanctuary where the chimpanzees are released out of doors for the first time.
The film directors discussed the decades-long odyssey of the chimpanzees and their carers with Josef Schmuck from the Documentation Center for Species Protection in Graz, Austria. The discussion was moderated by filmmaker Doris Metz.
