A maverick palaeontologist is expelled from his university for publishing his discredited research.
He camps out on the spot he's convinced he'll make an archaeological find that’ll change the course of our evolutionary history.
But what he discovers is more mind-blowing that anything he could have ever anticipated.
40 thousand years ago, in this place, many archaic human species co-existed peacefully.
Then us modern humans came along.
Why did all the other species become extinct?
And why - at that exact moment, did our DNA undergo an unexplained mutation – turning us from small-time hunter gatherers to the deadliest species the planet has ever seen?
