ONCE IN A LIFETIME - THE UNDERGROUND EIGER
United Kingdom / 1979 / 50'

Two young Englishmen Geoff Yeadon and Oliver "Bear" Statham decided to go along it, though it's a very risky adventure. The documentary illustrates the stages of the praparation for the expedition and the most exciting moments of this dangerous venture which the speleologists call the conquest of "The Underground Eiger".
