It was 30,000 years ago that Stone Age hunters painted some of humankind’s oldest works of art. Hidden away in remote caves in France, they portray the most important animal for our European ancestors: the aurochs. Extinct for centuries, this mythical creature shaped the continent’s landscape like no other. Today, labs using state-of-the-art technology are working on revealing the life of the “king of the wilderness”. This cinematic journey takes us from arid Spain to the mountain wilderness of Croatia, allowing us for the first time to see how wild aurochs contributed to the preservation of their habitat.
