A documentary film that tells the fascinating and incredible story of 13 Jewish survivors of the Holocaust in former Czechoslovakia, during the II World War. These men and women, that back then were children, found a legendary Jewish-German character named Fredy Hirsch, who changed their lives forever. The work describes the terrible living conditions in Terezin Ghetto and; on the other hand, the approach to culture and art behind the walls of the concentration camp. Up to this moment, everything develops as a known story, but by the end of 1943 there is an unexpected turn when these children are deported together with their families to the extermination camp in Auschwitz-Birkenau. And there, in the middle of hell, they lived in.
