Jungle Blue (1978)

The movie tells us the tale of Jane who is in search of her missing father in the jungles of Peru. She arrives in there with a group of friends including Silvia who has convinced Jane (by lesbian seduction we learn in one of many flashbacks) to let her and Hank join her on the trip. These two are posing as botanists searching for healing herbs in the jungle plant life but are actually in search of a hidden treasure of precious jewels that they believe are guarded by tribe Jane's father was studying. Once in the jungle they meet loin-clothed white man Evor who is called by native the lord of the jungle. Looking very Tarzan-like, Evor is a gentleman in every way and is the center of much spirited attention from both Jane and Sylvia. Inevitably, both get to "know" him soon.
