At the behest of his father, 17-year-old Erwin Rautenberg boarded a steamer for South America in 1937 to escape Nazi Germany. His brother, sister, and parents planned to join him, but never made it. His father died in 1938, soon after being
forced into the German army. The rest of the family was killed during the Holocaust.

As a documentary filmmaker, historian and curator, Christian Delage has long consulted with and used video testimonies of Holocaust survivors in his work.
