The Nuremberg Einsatzgruppen trial of 1947/1948 is considered the largest murder trial in history against members of four death squads from the security police and SD (the security service of the SS). During World War II, six million Jews were murdered. Four million died in the extermination camps, but two million people were killed in systematic mass shootings. A fact that is hardly known today. The perpetrators came face to face with their victims. They shot at men, women, children - day after day, obediently and assiduously, as if it were normal work. Tens of thousands of Germans belonged to the mobile commandos of the task forces and police battalions. Who were these men, how could they commit such murders? What did the few survivors tell, how were they able to escape the mass extinction and live on with the horrific experience? Based on written traditions, original documents, film footage and photos as well as expert statements, the documentary traces the path of one of these murder battalions.

Fifty years ago there were close to half-a-million lions in Africa. Today there are around 20,000. To make matters worse, lions, unlike elephants, which are far more numerous, have virtually no protection under government mandate or through international accords. This is the jumping-off point for a disturbing, well-researched and beautifully made cri de coeur from husband and wife team Dereck and Beverly Joubert, award-winning filmmakers from Botswana who have been Explorers-in-Residence at National Geographic for more than four years. Pointing to poaching as a primary threat while noting the lion's pride of place on the list for eco-tourists-an industry that brings in 200 billion dollars per year worldwide-the Jouberts build a solid case for both the moral duty we have to protect lions (as well as other threatened big cats, tigers among them) and the economic sense such protection would make. And when one takes into account the fact that big cats are at the very top of the food chain-and that their elimination would wreak havoc on all species below them, causing a complete ecosystem collapse-the need takes on a supreme urgency.
