Cinematic legend Werner Herzog presents an astonishing glimpse of our prehistoric forebears.

Kudos to Herzog (Encounters at the End of the World, MIFF 2008; Grizzly Man) for achieving the impossible - gaining access to the French Chauvet-Pont-d'Arc Cave, a place that only a handful of scientists had previously set eyes on. An astounding discovery, the cave contains 32,000-year-old artwork so fragile it could disintegrate from accumulated human breath.

Under limiting circumstances, Herzog and his small crew have filmed what he calls "one of the great discoveries in the history of human culture". Using 3D film technology to amazing effect, they give depth to every contour of the prehistoric canvases.

Combining his own enthusiastic narration with thought-provoking insights from scientists, Herzog delves into a fascinating exploration of art, spirituality and the very nature of humanity.
