The Lion Man takes Nina deep into the dark heart of Nazi Germany, where in a remote cave in late August 1939, archaeologist Robert Wetzel came across the 40,000-year-old artwork now known as the Lion Man.

Just a week later, WWII broke out, the excavation came to halt and, in one of the great mysteries of archaeology, Wetzel never mentioned his incredible find again.

As Janina discovers, the Lion Man represents a revolution in the human story. Half-man and half-animal, it is the first artwork created from the human imagination, revealing the very origins of human art, religion and culture.
