May 27-June 5 The extraordinary adventure of the young members of the Piedmont Speleological Group who, having already explored all the caves of Northern Italy, changed course in August 1961 and went South to explore other caves unknown to man, 700 meters below the Earth, in the untouched Calabrian hinterland. The intruders’ venture goes unnoticed by the inhabitants of a small neighboring village, but not by the old shepherd of the Pollino plateau whose solitary life begins to interweave with the group’s journey.
