The Face of Eve.

Adventurer and treasure hunter Mike Yates is hoping to find a cache of Incan treasure lost in the Amazon jungle. While looking for his missing partner, he stumbles across a beautiful jungle girl named Eve. Later on, he comes across Eve's grandfather, who is being swindled by a man and a young woman who is pretending to be his granddaughter Eve. Will Yates be able to expose the swindle, beat the swindlers to the lost treasure (with the help of the real Eve), and reunite Eve with her grandfather before the final credits roll?
