The Green Inferno is a visceral, brutal horror film that takes viewers deep into the heart of the Amazon rainforest, where a group of well-meaning activists find themselves facing unimaginable terror. The story begins with a group of college students, led by the passionate and idealistic Justine, who travel to the Amazon to support a campaign against the deforestation of the rainforest. Their mission is noble: they aim to protect the indigenous tribes and the natural environment from destruction by corporate interests.
However, their sense of adventure and righteous cause quickly turns into a nightmare when their plane crashes deep within the jungle. The group, now stranded in a remote and unforgiving wilderness, soon discovers that the very people they sought to help may not be the benevolent souls they imagined. They are instead caught in the violent grip of an isolated tribe of cannibals, whose ancient traditions involve brutal rituals and a terrifying taste for human flesh.
