This is about two men who go to save a woman who was kidnapped by South American savages. You see a lot of that in these older movies. Anyone who isn't white is a savage, hell-bent on sacrificing white women. There's got to be some real tribes that would do that, but 99% of them are probably chill. All they'd want to do is get you high with their mystical drugs and feed you.
Going into the jungle is scary. It doesn't matter how many guns you have. You could have a ballistic missile strapped to your back, but if the wrong mosquito bites you then it's all over. Or a giant flower eats you. Don't look at me like I'm crazy. There are species of plants we still haven't discovered yet. Why haven't we? Because everytime a human sees it, the plant eats them.
