This week the film Destination Unknown is released, a documentary that mixes testimony and archive to tell the stories of twelve Holocaust survivors who hid, fought as partisans, and endured camps such as Krakow-Plaszow, Mauthausen and Auschwitz-Birkenau.

The film documents the lasting effect on the survivors 70 years after liberation and includes the story of Ed Mosberg, who explains to the Today programme why the Holocaust will never be over for him.
