The Lost World - Season 2 Episode 10
The Source

The Lost World is in the grip of a crippling drought. Our adventurers are saved from a pack of thirsty Raptors by a magnificent young woman who begs them to escort her to her pueblo. She confesses that she is a survivor of the original colony, which had discovered the Fountain of Youth. Her supply is diminishing, however, and she must return to the Fountain cave--or die. Marguerite, with visions of eternal youth and wealth, leads the others after Ana.
