Susan Alison is a beautiful, ambitious woman who is after a legendary treasure of diamonds and emeralds, which are part of the ornament of a tribe of savages in the Ucayale river (a tributary of the Amazon). She flies to Iquitos, Peru, in the company of Hank Rollins, also an adventurer after the jewels. Jane Royce, a really beautiful girl, is also in the jungle looking after her father, a missionary lost while trying to convert the head hunters. They adventure into the jungle and meet Evor. Both girls are aroused to tremendous heights of passion and, one after the other, discover sex with a super human being. Hank convinces Evor to take him to the tribe in order to get to the jewels; once there, they poison the entire tribe, taking the jewels and Jane as a prisoner. Evor goes to rescue them, jungle style. Susan is attacked by a poisonous snake and Hank is caught by the piranhas; Jane is saved by Evor for a sensual rendezvous in paradise. Prior to this adventure, Susan and a group of Americans in Peru tried the Yassahuacca, a drug obtained from a tree bark which is capable of bringing the group into an incredible sex orgy. This orgy and the adventures are paralleled in the story of Jungle Blue, making it a very unique adult motion picture.
