It was a late summer day in France when Marcel took a walk through the woods. He was looking for treasure.

On September 12, 1940, a terrible war was being waged above ground.
But that day, Marcel climbed deep underground, following a hunch, and he found something that made him curious.
Eventually, he brought three boys with him.
They found something that left them amazed.
A discovery by these four teenagers made the world stop
and pay attention
and it forever changed the way we think about art,
animals,
and humanity.
