The People in the Trees

In 1950, a young doctor called Norton Perina signs on with the anthropologist Paul Tallent for an expedition to the remote Micronesian island of Ivu'ivu in search of a rumoured lost tribe. They succeeed, finding not only the tribe but also a group of forest dwellers they dub 'The Dreamers.' Who turn out to be fantastically long-lived but progressively more senile. Perina suspects the source of their longevity is a hard-to-find turtle; unable to resist the possibility of eternal life, he kills one and smuggles some meat back to the States. He scientifically proves his thesis, earning worldwide fame and the Nobel Prize, but he soon discovers that its miraculous property comes at a terrible price.
