September 1st, 1939. Nazi Germany invades Poland. The campaign is fast, cruel and ruthless. In these circumstances, how is it that ordinary German soldiers suddenly became vicious killers, terrorizing the local population? Did everyone turn into something worse than wild animals? The true story of the first World War II offensive that marks in the history of infamy the beginning of a carnage and a historical tragedy.

Countless people around the world know the pictures from Leni Riefenstahl's films, even if they have not seen them in their entirety. The work of the German director has burned itself into the collective memory. Even decades after the end of the Nazi era, she showed no remorse and presented herself as an apolitical, naive follower of the Nazi criminal regime. Her artistic service for the cinema was always recognized. But book author Nina Gladitz shows after decades of research that Hitler's favorite filmmaker was not only a follower, but also a perpetrator during the Third Reich, who instrumentalized other filmmakers such as the brilliant cinematographer Willy Zielke in order to gain fame for herself.

An exceptional documentary film that chronicles the liberation of Auschwitz, commencing on the day of liberation and backtracking in time to narrate the tragedy of the Holocaust from four distinct perspectives: the prisoners, the liberators, the perpetrators, and the local residents.
