S2·E4 The Legend of the Lost

Event: VANUATU ISLANDS 4800 B.C. Government agent Derek Lloyd, who tricked Sydney and Nigel into a mission once before, lures Sydney to New Guinea by kidnapping Nigel. Sydney and Nigel don't believe that the spy is on a goodwill mission, but are seduced by the possibility of rediscovering a lost civilization, the Kai Nomata, an ancient tribe believed to have been destroyed by a volcano thousands of years ago. When the need-to-know details are revealed, Sydney and Nigel don't know who or what to believe.
