Mendoza – a peaceful provincial town in Argentina at the foot of the Andes. The 8 April 1977 – the last day that Gisela Tenenbaum was seen alive. What happened to her after that date remains a mystery. How does a family continue to come to terms with the fact that their daughter – Gisi – disappeared so many years ago? Was she kidnapped, tortured, murdered? Gisi is gone and yet still present - a situation more painful than if she had died as a child. Erich Hackl has written the story of her family – Austrians of Jewish origin who fled to Argentina in 1939 –, of Gisi's committed struggle against injustice, and her desperate, underground work for a cause that would ultimately be lost.
