The tin cans left behind by a documentary crew that vanished in the humid and eerie depths of the Amazon rainforest bring to light the dark side of humanity, which claims to be civilized. Directed by Ruggero Deodato, this horror film goes beyond a mere rescue mission, plunging the viewer into the heart of the swamp and savage rituals. This found-footage film, which shows how boundaries dissolve while the camera is rolling, leaves the viewer alone in an eerie landscape where civilization clashes with the primitive.
