Description
Within the icy slopes of Mont Blanc, the highest mountain in the Alps, there exists a secret waterworld. In this program, scientists travel into these previously unexplored recesses to learn why, in 1892, one of Mont Blanc's hidden lakes burst forth, enveloping the villages below and killing 200 unsuspecting people.
