The Source (S02E10)

The Lost World and its inhabitants are plagued by a severe drought. When a pack of hungry, thirsty raptors attack the explorers, a beautiful young woman named Ana comes to their aid. She hopes that, in return, they will escort her back to her pueblo. Ana falls weak, however, and confesses that she and her ancient colony had discovered the Fountain of Youth and her supply is now diminishing. (Prime Video)
