Beyond tanks and territory, the Nazi regime pursued a stranger ambition: reshaping nature itself to fit its racial ideology. This film traces how Hermann Goering and Heinrich Himmler put Germany's leading scientists to work on breeding programs meant to resurrect extinct species and engineer an ideal 'Aryan' countryside. The centerpiece is the attempt to back-breed the aurochs, Europe's vanished wild ox, by selectively crossing modern cattle until their genes supposedly reassembled the ancient animal, intended to stock vast hunting reserves designed for a future thousand-year Reich. Archival photographs, wartime documents, and interviews with historians and geneticists lay out how far the scheme went, from planned settlement landscapes to livestock experiments that echo uncomfortably in some cattle breeds still around today. The film treats this less as a curiosity than as evidence of how deeply racial pseudoscience penetrated Nazi policy, reaching past human victims into forests, farms, and gene pools, and asks what became of the animals and ideas the regime left behind.
