Mankind has landed on the Moon and flies around in space. But under our feet there are about a million kilometres of cave systems – only one per cent of which has been explored. The film accompanies experienced cave explorer and mountaineer Lea Odermatt on her tours beneath the surface of the earth, in claustrophobic passageways and gigantic caverns.
